Flex text area issues... highlight an cursor position

2009-11-20T09:03:16Z

Hey guys,

I'm struggling with a couple of things with a flex text area.

I'm accustomed to the JTextArea control from Swing... and I can really
very easily create a highlighter and tell it to highlight a certain
span of text... I'm not seeing a good way to do this with a Flex
textarea.

Second, I'm used to being able to ask a text area for the position of
the cursor in the text, so that I can insert characters @ that
position. I haven't been able to figure out how to recreate that
behavior in Flex.

Ideas?

Willy

Synchronized Video Playback

2009-11-11T20:42:04Z

Hi,

I am creating a synchronized playback experience for a group of users around
a video. I don't have control over the video player, so I am writing a
protocol where the different users send messages to each other to stay in
sync.

Does anyone have experience doing something similar, or seen a similar
problem solved? Any point of reference would be extremely helpful.

Thanks,

Karthik

Re: AS convention: Public member variables?! What of encapsulation?

2009-11-10T13:12:33Z

@barneyb, maybe I'm just being a curmudgeonly Java engineer, but it
still gives me the creeps to see all those public members. I see your
point, though. By using the implicit getters and setters only as
needed I can change the functionality without changing the "signature"
of the class. This seems to assume, however that most setters are
simply {this.myVar = myVar;}, and are actually a waste of time. I'll
concede that many of them may be, but they're generated, and I don't
actually have to write them. I see the value, in a shared-code
environment of being able to add the setter without having to update
calling code.

@Paul, We're using BlazeDS with Tomcat, and it's the same way... It
expects the AS class to have the public properties. But that seems to
me to be more of a response to the established convention rather than
something that's inherent to the AMF communications. They could
just as easily used a Beans kind of approach and retrospected the
class for set*() and get*(). Doesn't Mach-ii do that on its beans?

Anyway, thanks guys, nice to at least hear a well-reasoned response
to the question I actually asked. Usually when I bring this up the
answer I get is, "You want setters? Just write 'em, and leave me
alone!"

help with picking up dynamic url

2009-11-10T12:59:45Z

Basically, I am trying to get the url from the application, and set some rules so that flex will call the right ColdFusion template depending on what server this application is running on like dev, staging or production. The application is for uploading a csv file. A coldfusion page reads some values from the csv file, and inserts/updates some db records.

I have the following:

[Bindable] private var _strDomain:String = new String("http://dev.domain.com/");
[Bindable] private var _strUploadScript:String = new String(_strDomain + "ubs/upload.cfm");
private var unid:int = 0;//Application.application.parameters.unid;

// Initalize
public function initApp():void {

_strDomain = mx.core.Application.application.url;
var index:int = _strDomain.indexOf("/Intranet");
_strDomain = _strDomain.substr(0, index);
_strUploadScript = _strDomain + "/Intranet/ubs/upload.cfm";

mx.controls.Alert.show('a:'+_strUploadScript);
Security.allowDomain('*');

there are several issues. if i get rid of all the stuff in initApp and run this in dev by calling:

http://dev.domain.com/ubs/upload.cfm

it works great.

It doesn't seem like initApp() changes the _strDomain, _strUploadScript right. If i get rid of the above vars, then I get all sorts of 'access of undefined property errors'.

The initApp is called by creationComplete="initApp()". I am new to flex 3/as 3 and cannot resolve this issue. What am I doing wrong? thanks in advance.

As well as for VO's back to ColdFusion they need to be public.

Subject: Re: AS convention: Public member variables?! What of encapsulation?

ActionScript, unlike Java, lets you transparently override public
properties with implicit getters and setters. So you can start with a
public property, and then later decide to use a getter/setter pair
without changing the API of your class. With Java, you can't do that,
so you HAVE to declare the getter/setter pair up front.

As a concrete example:

public class Person {
public var name:String;
}

can be used like this:

p = new Person();
p.name = "fred";
trace(p.name);

Later, you can change the class to this:

public class Person {
private var _name:String;
public function get name():String {
return _name;
}
public function set name(name:String):String {
_name = name;
}
}

After doing that, you can still reference the class in exactly the
same way as before; ActionScript takes care of the implicit
getter/setter magic internally, so you don't have to worry. The net
is that you're not sacrificing encapsulation, you're just not having
to write a bunch of boilerplate code until you actually need to.

Display nested objects within tree?

2009-10-29T08:38:34Z

Hey All,

Suppose I have a simple class, node.as.

It has two properties:

name:String;
childNodes:ArrayCollection; //contains more node objects
//which may contain even
more node objects.
//these will be built up
recursively.

What's the best way to display this in a tree control? Can I specify
label and children fields in the Tree declaration?

Subsequent remoteobject call will fail

2009-10-12T01:06:58Z

Hi all!

I have a problem integrating Flex 3 - CF8.
Server platform: Debian/CF8/Apache2/MySql

On this server, I have 2 separate virtual host/website, say "dns_service_one" and "dns_service_two".
In each of these, I have a CF application with a test CFC (see code below).
Session managament are enabled in applications.

In a test Flex application, I call each of two service exposed by the server.
The problem is that the second call always fail, returning the error below.

Note that separate call will success. The remote service is up and working.
If I invert call order I obtain the same error.

I I move one service into another server with same configuration, the application works well.
It seems that I can't call 2 separate service into 2 separate CF application on the same server from a single Flex app ?

Code is below.
Sorry for the length of my question.
Thanks for help.

PDF conversions

2009-10-11T13:55:50Z

Slightly OT for this list, but since my frontend is Flex and backend
CF I thought I'd ask:
I'm looking for a good PDF to Image conversion system. I need to
ingest PDF documents after user upload and basically convert them to a
flat (JPG for example) image. The conversion needs to happen serverside.

I know that I can find a lot of such tools via Google, but I would
prefer a recommendation.

Regards,

Stefan

Thanks. I think you are right. I've tried other suggestions - and it only works if it is in a CFM page.

I think what you ned to do is do a URL request to a .cfm We pop a new
windows and call a .cfm page for our reports from flex.

If ColdFusion is your backend you can use ReportBuilder:

actually, still no.

<mx:Style>
FormItem {
labelStyleName: labelStyle;
}
.labelStyle{
textAlign: left;
}
</mx:Style>
<mx:Form>
<mx:FormItem label="Name">
<mx:HBox>
<mx:TextInput id="firstName1" />
<mx:TextInput id="lastName1" />
</mx:HBox>
</mx:FormItem>
<mx:FormItem label="Email">
<mx:TextInput id="email" />
</mx:FormItem>
<mx:FormItem label="Fixed Total Charge:" width="100%">
<mx:TextInput id="fixedChg" width="50%" />
</mx:FormItem>
<mx:FormItem direction="horizontal" width="100%">

<mx:FormItem label="Fixed Total Charge: aaa" >
<mx:TextInput id="fixedChga" />
</mx:FormItem>

<mx:FormItem label="Per aaa" >
<mx:TextInput id="perUnita" />
</mx:FormItem>
<mx:FormItem label="Fixed Per Unit Charge aaa">
<mx:TextInput id="perUnitChga" />
</mx:FormItem>
</mx:FormItem>
<mx:FormItem label="">
<mx:Button label="Submit" />
</mx:FormItem>

</mx:Form>

see, how fixed total charge (formitem label) and fixed total charge: aaa (formitem label) are not vertically aligned? Fixed total charge: aaa (formitem label) starts right under the textbox. I need to push it to left a bit more.

Re: pre-selecting some rows in a DataGrid

2009-09-04T13:56:34Z

Checkout selectedItemsCompareFunction, might help you there. Also, in your
attempts, I'd build a array of these selectedItems of your own, then set
selectedItems = yourArray at the end. Each change to selectedItems throws
events.

Look here

pre-selecting some rows in a DataGrid

2009-09-04T09:24:17Z

Hey All,

Here's my current boggle:

I have a datagrid on a form that contains all possible selections. Say, for
example, I have a pizza order form, and I have all the possible toppings in
a datagrid.

Now, when the user multi-selects the toppings, and submits the order, I'm
capturing the data just fine. n number of toppings get inserted into the
database.

When I try to "review" the order, I'm sending down a VO from the server that
contains all the form data, plus an ArrayCollection of topping VOs. I'm
struggling with selecting the correct toppings in the datagrid.

Here's basically what I'm doing...

for (var i:int = 0; i<allToppingsData.length; i++) //loop over the array of
all toppings {
for (var j:int=0; j<inputVO.toppings.length; j++)//loop over the
toppings in the VO
{
if (allToppings[i].toppingID = inputVO.toppings[j].toppingID)
{//current topping in the VO matches the topping in the all toppings
list
toppingDataGrid.selectedItems =
toppingDataGrid.selectedItems.concat(toppingDataGrid.dataprovider[i];
}
}

This, unfortunately, isn't worth the paper it's printed on. Doesn't seem to
work at all. Anybody got any ideas?

Re: Components in tabNavigator not initialized

2009-08-27T08:30:52Z

"So in your case the form in
tab one would throw a event up to the parent of the Tab Navigator where a
event handler can then set the properties in the secondary tab. "

Yeah... It's hard to know how to simplify an example for posting
sometimes... Tab 1 is dispatching a custom event full of VO. It gets
to the parentApp, where an eventListener has been registered to pass
it to a handler. The handler tries to set the values and properties
on Tab 2, and this is where I was hitting the null pointer exceptions.

"Your approach is basically the same as
creationPolicy="all". This maybe ok if 100% of your users will interact
directly with the secondary tabs. "

" It is in
this handler you could use createChildrenFromDescriptors() on the second
tab, then set the properties"

That makes pretty good sense to me, though I am in a position to
guarantee that 100% of the users will run the tabs in question. Your
point is well taken, though. Only bring up the children as they're
needed... put it in a conditional (tab2==null or something?) at the
top of the event handler that handles the assignment from tab 1 to tab
2.

I respectfully retract my earlier assertion that you were only
"partly" right! ;)

(8(|) - D'oh!

Re: Components in tabNavigator not initialized

2009-08-27T06:21:37Z

no, I'm quite right :) I had written 'such as creationComplete', there are
other useful events available too. Your approach is basically the same as
creationPolicy="all". This maybe ok if 100% of your users will interact
directly with the secondary tabs.

" I need the selections on the first component (which is
created when the tabNavigator is created) to set values into a form on
the second component."

This is alarming. Your component in Tab one should never reach out to a
component in Tab two. Use events to communicate data upwards. Use
injection to communicate properties downwards. So in your case the form in
tab one would throw a event up to the parent of the Tab Navigator where a
event handler can then set the properties in the secondary tab. It is in
this handler you could use createChildrenFromDescriptors() on the second
tab, then set the properties. Or just set the selectedIndex and a anonymous
function handler on creationComplete to inject the variables. Or heck, use
binding! Binding is great in these situations.

Jeffry Houser has a nice preso around on Bullet Proofing your components
that maybe useful here. I don't have a link handy to the first part of this
preso though, sorry.

Re: Components in tabNavigator not initialized

2009-08-26T08:40:02Z

Hey DK,

You're partly right. In my example, I only had the two tabs, but in
my production app, I have many more, and they're all making REST calls
periodically once they've been created. The creationPolicy idea was
perfect for my example... but not so good for my production problem.

creationComplete, however isn't exactly the solution either, in this case.

I have two UIComponents with lots of children, nested within a
tabNavigator. I need the selections on the first component (which is
created when the tabNavigator is created) to set values into a form on
the second component. Unfortunately, it isn't created until its tab
is clicked. So... I could use it's creationComplete to go to the
first component, examine it, get the values I need, but then, when the
first component changed, I'd still need to have a method to set the
new values...

The solution I've settled on, which I discovered on the same pages as
the creationPolicy documentation is the createChildrenFromDescriptors
method. Basically:

parentApplication.creationComplete(function (){
mySecondComponent.createChildrenFromDescriptors();
anyOthersIReallyNeed.createChildrenFromDescriptors();
};

Does that seem reasonable?

Re: Components in tabNavigator not initialized

exactly what you don't need actually. :) Although that may work for you,
its not a good practice as this turns off the deferred instantiation
inherent to TabNavigator among others components. This means that all your
tabs are created immediately regardless if they are ever viewed, slowing
startup times. Better to use other event such as creationComplete, etc.

If I'm following you, I think you need to look into the creationPolity
property.

Hey guys,

Here's the issue:

I have a tabNavigator that basically looks like this:

My problem is that I need all the components in all the tabs to be not
null from the very beginning. I need, for example, to be able to set
details.addEventListener() in the creationComplete function of the
application... but details is NULL until it's been clicked on.

One way might be to refactor the creation of everything here into
actionscript, but it would be a long and tedious refactoring, and I
don't have the time. Thoughts?

Components in tabNavigator not initialized

2009-08-24T09:58:06Z

Hey guys,

Here's the issue:

I have a tabNavigator that basically looks like this:

<mx:TabNavigator id="tn" >
<mx:Canvas id="masterListTab">
<myComps:MasterList id="masterList"/>
</mx:Canvas>
<mx:Canvas id="detailTab">
<myComps:Details id="details"/>
</mx:Canvas>
</mx:TabNavigator>

My problem is that I need all the components in all the tabs to be not null from the very beginning. I need, for example, to be able to set details.addEventListener() in the creationComplete function of the application... but details is NULL until it's been clicked on.

One way might be to refactor the creation of everything here into actionscript, but it would be a long and tedious refactoring, and I don't have the time. Thoughts?

Thanks,

Willy
