Re: Re: is Html Page with XForm tags processed by Orbeon XForm engine?

Alessandro,

Thanks for your reply. But, I couldn't find xforms-epilogue.xpl in orbeon war
file (Orbeon 3.7.1 developer release). Or Do I need to create one?

Here is what I am trying to achieve.
I am planning to develop a portal application based on workflow engine and
Orbeon forms. I will have 2 portlet apps: one is Orbeon Forms (already
available) and the other is my app. My app will use Orbeon X-Form Engine to
process/submit forms and generate browser content.

In my portlet app, I can not control <head> tag of my portal page. I can
control only what my portlet can render and that's in <body> tag. In this case,
<XForm:model> tag will be in <body> tag. So, I was trying to find a way to
tell Orbeon XForm Engine to process XForm and generate Html.

Thank you very much.

Ketan

Alex,

this problem appeared in recent builds, however, it seems to have disappeared with the latest Orbeon Forms dev-post-3.7.1.200910090100

Correct. You should not be able to submit an instance if it contains
empty nodes marked as required.

You should be getting an alert in that case. I just test this in an
example, and it is working fine for me. If you still have this
problem, could you submit a simple example that shows this and runs in
the XForms sandbox?

If you know your code is always updating the instance in model1, you
could have in model2 a <xforms:bind calculate="..."/> that copies over
a values from an instance in model1 from an instance in model2. To
access an instance in another mode, use
xxforms:instance('my-instance-id').

Right now, when the page loads, the tree widget opens the branches so
that the selected leaves are visible. Other than that, you have no
control in XForms on what is opened.

But, as you suggest, you can run your own JavaScript on
xforms-model-construct-done that opens branches of the tree as
desired. You'll just need to have access to the JavaScript object
representing the tree, which as it happens is quite simple as it is
stored in ORBEON.xforms.Globals.treeYui["myControlId"] where
myControlId is the id you put on the <xforms:select> or
<xforms:select1>. And for more on the YUI tree, see:

http://developer.yahoo.com/yui/treeview/

It would be even better if you didn't have to write JavaScript, and if
the open/close state for branches could be stored in the instance.
That would be something to implement.

I am not aware of an issue with the HTML editor in repeats. Could you
attach a test a simple/minimal case that runs in the XForms sandbox
and that we can use to reproduce this?

The XForms engine only runs if it finds a
/xhtml:html/xhtml:head/xforms:model (the test is in
xforms-epilogue.xpl). But just changing this might not be enough to
make the XForms engine work on a document in which HTML elements are
in no namespace.

But I am not convinced that this is a good thing to do anyway: there
isn't much of a downside in putting "xhtml:" in front of the elements
name, and if the syntax bothers you, you can always define the XHTML
namespace as the default namespace. The serializer will remove that
namespace when the page is sent to the browser, so the namespace will
only be there in your files, making explicit what element is in what
namespace.

You are interested in this to make sure that the XHTML you produce is
compliant? Having a <span> around the <input> doesn't break
compliance, as far as I can tell.

(And <input> is in the "phrasing content" category [1], and the
content of a <span> can be "phrasing content" [2].)

Not that your example was wrong, but it was over complicated. Here is
the code updated to use the <xforms:group ref=".[condition]"> to hide

is Html Page with XForm tags processed by Orbeon XForm engine?

2009-10-09T10:18:49Z

Hi All,

I am new to Orbeon Forms. I am working on CreditCardVerify XForm (Sample XFrom
provided by Orbeon Forms -- I removed xhtml and put html tag). Below is source
code for the same. This file contains HTML + XFORM. As I have put Html tag,
XForm tags are not processed by Orbeon XForm engine. But if I put XHTML +
XFORM, it works fine.

==Source Code for CreditCard XForm ==

is Html Page with XForm tags processed by Orbeon XForm engine?

2009-10-09T09:57:01Z

Hi Group,

I was working on CreditCard XForm provided by Orbeon Forms app. Here is source code for the same. creditCard.jsp. This file contains HTML + XFORM. As I have put Html tag, XForm tags are not processed by Orbeon XForm engine. But if I put XHTML + XFORM, it works fine.

"XForms processing is triggered when either a legacy XForms model is found on the xforms-model input of the epilogue, or when an XForms model is found under /xhtml:html/xhtml:head. " - This is provided on Orben Form user guide. (http://www.orbeon.com/ops/doc/reference-epilogue -- "6. XForms Processing")

I would like to know, how to make Orbeon XForm engine to process HTML + XFORM.

Antw: Re: Pluto: Portlet deployment

2009-10-09T06:44:13Z

Hallo

I recently asked if anybody has experiences including Orbeon XForms in
a Pluto Portal.
I got it running, but quick and dirty. If somebody has a nice solution
i would love to know it.

I want so share my experiences:

web.xml
I used the filter: http://www.orbeon.com/ops/doc/reference-xforms-java

The filter didnt work by default. I had to add
<dispatcher>INCLUDE</dispatcher>.

XFormsPortlet.java
I tried two ways to include XForms:

1. context.getRequestDispatcher(VIEW_PAGE).include(request,
response);

OrbeonXFormsFilter.java
Because the pluto framework already called the PrintWriter the
ServletOutputStream cant be used.
I put the content of the OutputStream in the PrintWriter to get it
running.

// write rendered XForm
String content =
responseWrapper.getServletOutputContent();
content = content.replace("/pluto/orbeon", "/orbeon"); //
todo: hack -> find better way
servletResponse.getWriter().write(content);

2. request.setAttribute("oxf.xforms.renderer.document", xform);

OrbeonXFormsFilter.java
The attribute "oxf.xforms.renderer.document" set in doView() gets
encoded by Pluto. In OrbeonXFormsFilter.java i cant read the attribute
out by default.
The attribute looks like
Pluto_testsuite.XFormsPortlet!-577071127|1_oxf.xforms.renderer.document.

I made a hack in OrbeonXFormsFilter.java to get it running:

// Set document if not present AND output was intercepted
if (!requestWrapper.hasXFormsRendererDocument()) {
final String content = responseWrapper.getContent();
if (content != null) {

httpRequest.setAttribute(OPS_XFORMS_RENDERER_DOCUMENT_ATTRIBUTE_NAME,
content);
}
} else {
String contentFromAtr =
requestWrapper.getXFormRenderDocument();
if (contentFromAttr != null) {
if (contentFromAttr != null) {
responseWrapper.getWriter().write(contentFromAttr);

httpRequest.setAttribute(OPS_XFORMS_RENDERER_DOCUMENT_ATTRIBUTE_NAME,
contentFromAtr);
}
}
}

Issue when adding html editor inside repeat control

2009-10-09T03:21:45Z

Hi,
I'm using an html editor inside a repeat control.
<xforms:textarea ref="notes" mediatype="text/html">
When I click on the add button to add a 2nd row, orbeon throws
an
exception as follows:
Exception in client-side code.
Message: 'undefined' is null or not an object
Is this a bug? Please help in resolving this

Thanks in advance

xxforms:tree All Nodes Expanded

2009-10-08T05:56:48Z

Select1 control with appearance="xxforms:tree" by default generates the Tree control with all nodes collapsed. I would like to see all tree nodes expanded when the corresponding page is displayed. How can I acchieve this? Maybe some Javascript code in xforms:ready action?

update multiple models

2009-10-08T03:36:34Z

Hello everybody,

I'm wondering whether there is a way to update nodes in different models at the same time.

What I'm actually meaning is that I refer (with an inputText for instance) to a node in model1 and if the user changes something, this value should be updated in the referenced node in model1, but also in a node in model2...

So, is there a possibility to hook-up nodes? And then; even over different models....

Best regards,

Bart

org.dom4j.DocumentException Xerces?

2009-10-08T02:30:04Z

Dear list, I wonder if someone could help me with the following error:

2009-10-08 10:10:10,318 ERROR ProcessorService - Exception at (re-initializing XForms containing document)
org.dom4j.DocumentException: Can't find bundle for base name orbeon.apache.xerces.impl.msg.SAXMessages, locale en Nested exception: Can't find bundle for base name orbeon.apache.xerces.impl.msg.SAXMessages, locale en

I am seeing other problems - ClassDefNotFound - with Xerces as well. They occur after Tomcat has apparently started up successfully and temperamentally, ie they don't always manifest themselves in the same place consistently.

As well as Tomcat 5.5.27, two other applications loaded use Xerces on my Solaris 10 system. java -version gives me

java version "1.5.0_17"
Java(TM) Platform, Standard Edition for Business (build 1.5.0_17-b04)
Java HotSpot(TM) Server VM (build 1.5.0_17-b04, mixed mode)

I'm not really familiar with Java so I'm having trouble finding the cause of the error and eliminating it. I'm aware that there is a wealth of documentation out there on Tomcat, classloading etc - but I wondered if anyone would be kind enough to give me a head start in solving this.

Full error log attached.

Thanks,

Tom

The XSLT step occurs in page-flow epilogue.

http://www.orbeon.com/ops/doc/reference-page-flow#accessing-submission

It's not completely clear to me because I don't use the feature
this way... but I believe that to access the data in XSL from a
submission, it must have the attribute replace="all" which will
refresh the page and hence re-process it the XSLT.

That's all I can offer at this time.

Sure thanks.

IE client side issue - form submit using go uri

2009-10-07T14:57:06Z

In a fresh IE 6, 7 or 8(deleting browser history, cache) , if form is submitted, i am getting

Exception in client-side code.
Message: Object required

Debugging in further its showing error in xforms-dialog-yuicalendar-min.js at line 89 char 1380443. This issue occurs only first time, on same browser submitting the same form second, third..... has no issues.It will pop up with a dialog "your information has been submitted, thank you" with ok link to go to uri xpath url

Following are the properties
<property as="xs:string" name="oxf.fr.detail.submit.buttons.*.*" value="go"/>
<property as="xs:string" name="oxf.fr.detail.submit.go.uri-xpath.*.*" value="//gourl"/>

Can anyone give some direction on how to fix this IE issue. Firefox works fine all the time.

Re: Required attribute

2009-10-07T13:28:12Z

Figured it out ... in fact I am not able to save an empty field when
required is true.

But, I'm not getting an alert message from

<xforms:input ref="title">
<xforms:label>Title</xforms:label>
<xforms:alert>The title is required</xforms:alert>
</xforms:input>

Should I be? Or is there another missing piece I should be aware of?

Thanks

Re: Re: Re: hierarchical forms without nested XForms controls in Orbeon

2009-10-07T11:30:51Z

Okay, maybe I am quite a bit more lost than I had originally thought.

How can the XSLT engine access XForms instance data without using an XPL model, and purely relying on an xforms:submission? I do know that, for example, using <xsl:if> statements can only see variables within the XSLT context and not the XForms context. Once a submission occurs, how then can the XForms data be retrieved by XSLT statements?

Maybe this would help everyone understand where I'm coming from. I've attached a simple example to this message illustrating where I am with trying to implement a basic recursion mechanism based on XSLT (using the idea of "repeats within XSLT" that Alex had mentioned in a previous reply to this thread). Citeinfo.xbl is where the recursion is supposed to happen. It's a number of files, so it can't be run in the sandbox, but I'm able to run it using http://localhost:8080/orbeon/xforms-xbl-test/.

Mainly, I'd like to know where I'm going wrong with my approach to the problem based on my code, and if a XForms/XBL approach is possible with this problem (with traces of XSLT), or if I'm going to need my XBL components be XSLT stylesheets instead.

Thanks again for your insight Hank, and in advance to anyone else who can help shed some light on this.

Because xlst is a processing step that is performed before the xhtml is
given to the xforms engine, it is a little unclear what order things
will
happen here. You can use xslt to create the xbl and xf elements but not
the other way around.

Also, the xslt must be specifically given data, it does not have access
to any model/instance except by submission, default submission or an
xpl model.

Cheers,
Hank

Using FF 3.5.3 and Orbeon 3.7.1.2, I'm getting unexpected results with:

<xforms:bind nodeset="book">
<xforms:bind nodeset="title" required="true()"/>
<xforms:bind nodeset="author" required="true()"/>
</xforms:bind>

I am able to Save a book record with empty title and/or author fields.

I'm following the tutorial carefully but I note that the example source uses
the XPath "instance('books-instance')/book"). This also fails in my form. My
instance seems correct. Any ideas?

Thanks

Hi Erica

Thanks for your explanation. It makes a lot of things clear.

Re: Re: hierarchical forms without nested XForms controls in Orbeon

2009-10-06T16:58:42Z

Thanks for the reply, Hank. :-) I think I've got a better understanding of what to do now, and I've been able to incorporate generic XSLT in my forms. That leaves me with one (hopefully) final question.

I have a nested XBL component structure that looks like this (where each XBL component is represented by fr:n):

---CONTENT OF FR:1---

<xf:repeat>
...XHTML content...
<fr:2 />
</xf:repeat>

---CONTENT OF FR:2---

<xf:repeat>
...XHTML content...
<fr:3 />
</xf:repeat>

---CONTENT OF FR:3---

<xf:repeat>
...XHTML content...
---WHERE I WOULD LIKE RECURSION TO HAPPEN (perhaps have <fr:1 /> be placed here?)---
</xf:repeat>

For actually implementing the recursion mechanism, I was wondering if it was possible to place the <fr:1> component inside <fr:3> without a StackOverflowError. Can variable tracking be possible in this case, such as a variable that knows when to stop the recursion? Or is there no choice but to implement something like this:

<xsl:if test="$recursion-level = 1">
<fr:recursion1 /> <--- XBL component that reflects a repeat structure that recurses once
</xsl:if>
<xsl:if test="$recursion-level = 2">
<fr:recursion2 /> <--- XBL component that reflects a repeat structure that recurses twice
</xsl:if>

...

Thanks in advance for any help or suggestions offered! :-) And please let me know if anything I said is unclear.

If you do a replace="all" then the whole page will be refreshed. The
state
of all your models will be lost, about the same as if the user
clicked refresh.
If there is any other data you need to carry over, then you will need
to pass
that as well in the submission or use session listeners, etc.

No. If your page is the view="" attribute, and it contains the XSLT
namespace:

xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xsl:version="2.0">

Then it will be processed by page-flow controller. You can use any
xsl elements.
<xsl:for-each> is convenient.

I'm not ready to comment on the rest of this, except to say, look at the
explanation for the pfc

http://www.orbeon.com/ops/doc/reference-page-flow#default-submission

Your submission can point to the same target as your page.

Hank

RE: Cant understand what i did wrong

2009-10-06T16:09:42Z

Hi Sridanu,

Because your model has more than one instance, you need to make sure you specify which instance you're referring to with your "nodeset" or "ref" attributes.

For example, you have this line:
<xforms:repeat nodeset="parameter" id="parameter-repeat">

Which is referring to the "parameter" nodes in the "parameter-instance" instance block. It should probably look like this:
<xforms:repeat nodeset="instance('parameter-instance')/parameter" id="parameter-repeat">

Because the instance hasn't been specified in the first example, Orbeon is trying to find all the "parameter" nodes in the default instance, which in this case is the first one it finds - the "function-instance". There are no parameter nodes in the "function-instance" instance, so it repeats zero times.

When you removed the "function-instance" instance block, the "parameter-instance" node became the default (as it was now the first one in the list) and so the repeat block started to work.

Regards,
Erica

Re: Re: Using Captcha component in XForms page

2009-10-06T09:27:57Z

Thanks Alex and vincent for your responses.

For a short term solution I used the math Captcha suggested by Vincent.

Now I need to go through XBL component and then I implement later using XBL.

Vincent: Is there any simple way to generate Random text instead of Random number ?

Hi,

Below an example of a "Math Captcha" in XForms
(it would be nice if it could be embedded in a XBL component in Orbeon
Forms):

In the model :

<xforms:instance id="captcha">
<instance xmlns="">
<value1/>
<value2/>
<sum/>
</instance>
</xforms:instance>

<xforms:action ev:event="xforms-ready">
<xforms:setvalue ref="instance('captcha')/value1"
value="xs:integer(random()*20)"/>
<xforms:setvalue ref="instance('captcha')/value2"
value="xs:integer(random()*20)"/>
</xforms:action>

<xforms:bind nodeset="instance('captcha')/sum"
type="xs:positiveInteger" constraint="number(.) and
number(instance('captcha')/value1)+number(instance('captcha')/value2)=number(.)"/>

Next in the body :

<xforms:group ref="xxforms:instance('captcha')">

<fieldset>

<legend>Math Captcha</legend>

<div class="ori-category-help">Afin déviter des soumissions
automatisées et intensives réalisées par des robots malveillants, nous
vous demandons de bien vouloir répondre à cette simple question
mathématique avant de valider le formulaire.</div>

<xforms:output ref="value1"/> + <xforms:output ref="value2"/>
=
<xforms:input ref="sum" incremental="true">
<xforms:label class="hidden">Math Captcha</xforms:label>
<xforms:alert>ne correspond pas à la somme attendue</xforms:alert>
</xforms:input>

</fieldset>

</xforms:group>

Vincent.

xforms:insert help

2009-10-06T08:27:55Z

Hi,
I'm trying to switch a form over to Orbeon and need to replace where I use xforms:copy with xforms:insert. I'm having a lot of trouble figuring out the correct syntax for this particular use (although I use xforms:insert in other places without any problem at all). Maybe someone can give me a hand?

I have 3 instances, the working instance "metadata" a instance for creator roles called "roleShort" and an empty instance I have been using to save copied role nodes into called "addRole". The original version of the form used a select1 populated by the roleShort instance, the selected role node was then copied to the addRole instance and then using an add trigger was eventually added to my main working instance "metadata"

Here is what it looks like with xforms:copy

            <xforms:instance id="addRole">
                <mods:mods>
                    <mods:role/>
                </mods:mods>
            </xforms:instance>
            <xforms:instance id="roleShort">
                <mods:mods>
                    <mods:role>
                        <mods:roleTerm authority="marcrelator" type="code">art</mods:roleTerm>
                        <mods:roleTerm authority="marcrelator" type="text">Artist</mods:roleTerm>
                    </mods:role>
                    <mods:role>
                        <mods:roleTerm authority="marcrelator" type="code">aut</mods:roleTerm>
                        <mods:roleTerm authority="marcrelator" type="text">Author</mods:roleTerm>
                    </mods:role>
              </mods:mods>
         </xforms:instance>


<xforms:select1 ref="instance('addRole')/child::*">
    <xforms:itemset nodeset="instance('roleShort')/child::*">
          <xforms:label style="display: block;" ref="mods:roleTerm[@type='text']"/>
          <xforms:value ref="mods:role"/>
      <xforms:copy ref="."/>
      </xforms:itemset>
</xforms:select1>


<xforms:trigger class="add">
    <xforms:label>Add</xforms:label>
    <xforms:insert ev:event="DOMActivate"
                  context="instance('metadata')" nodeset="instance('metadata')//mods:mods/mods:name[index('name')]/child::*"
                   at="index('roleInfo')" position="after" origin="instance('addRole')/child::*/child::*"/>
</xforms:trigger>

I have tried several different itterations of xforms:insert within the select1 statement but have had no luck? Any pointers would be very helpful!
Thanks,
-Winona

Re: Calling session-destroyed.xpl when logout from liferay

2009-10-06T07:50:28Z

Thanks Alex for your reply.

It used to work in stand alone environment without liferay.

Now I fixed this one in liferay also. The problem was happending because of the below two lines in liferay-portlet.xml

<private-session-attributes>false</private-session-attributes>
<private-request-attributes>false</private-request-attributes>

when I commented out those two lines, it is working as expected.

Since you mention Liferay, I have to ask: is this happening only when
you deploy Orbeon Forms as a portlet, or also when you deploy it as a
regular web app (servlet)? If it happens as a web app, can you
reproduce the issue with a plain Tomcat (it is easier for us to
reproduce issues on Tomcat).

Maybe I can look into that day extending machine. I've been told I'm pretty handy.

My comments were not meant to offend you or your team. I was simply looking to see if anyone in the community had successfully gotten form runner to work within liferay since it appears like you've documented that it works based on the link below.

In essence, at this point, no, Form Runner / Form Builder is not
regularly tested on Liferay. Until someone invents a machine that adds
a few hours to every day, we can only afford to do testing on Tomcat,
and we can only fix issues in other application servers or portal
containers that are reported by our clients who have a Development
Support plan. We got Form Runner to run on Liferay in December 2008,
but unfortunately, it looks like we must have introduced something in
the meantime that breaks it.

RE: Re: RE: Re: Custom XHTML output for XFORMS elements

2009-10-06T02:08:24Z

Thanks Alex, for your reply, but this doesn't really suit our needs, since we have to comply with the html that's delivered by our interaction designers. This html does not contain span elements for form controls and so on... I'm afraid that we just have to conclude that it's not possible for now to have Orbeon deliver fully compliant xhtml.

If you just add a class attribute, say: <xforms:input class="gaga">,
than that class is carried to the span around the control. You can
then style the input with:

.gaga input {...}

Would that be good enough?
