Problem Sumitting Struts Form containing a drop down list <html:optionsCollection>

[Hanen Ben Rhouma]

Please, I need your help: I've spent more than one week on trying to figure
out how to submit a struts 1 form containing a drop down list (using
optionsCollection). The problem is that the items in the optionsCollection
refer to the action assigned to the form while I need that same action to
submit my form and trigger the forward to another jsp page.


I'm loosing my cool temper in front of such futility, any ideas PLEASE???

[Kawczynski, David]

I'd love to be able to help but am confused with what you are having
trouble with.  I think I heard something about wanting to modify the
action of a form based on the value selected in a drop-down.  I also
heard something about forwarding to another jsp page.  If you can
clarify your intent you may end up with a good pointer or two.

Morning,

If I give code details, no one will show interest with so much details and with only the description of my requirement no one also could understand, that's pretty complicated you know!!

Well, let me represent it with another approach, by screeshots maybe is better (please take a look at my jsp page shown in the attached screeshot). By selecting one change ID I'd like to forward my form to another jsp page representing the details of the selected change (description, change number, creation date, user, workspace...).

The problem is that I'm either using dojo to code the drop down list from user side (and the mapping between simple <input> parameters and a struts form <html:form> isn't that trivial to do), or I've tried also to code it from server side (eventhough it's too slow) by using a struts form <html:form action="someAction"> containing <html:optionsCollection> to represent the dynamic drop down list (here the problem is that <html:optionsCollection> will make use of the struts action "someAction" to retrieve the data necessary to fill the drop down list and not to code the form's behavior after submitting it.

Hope that my point is clearer this time, I'll be really grateful if someone got a clue to all this headache :(((

Regards,
Hanen

Hi Hanen,
firstly I see no attachements, maybe because they are deleted by
mailing list itself.
Secondly, if the problem You have is hard to explain,
then maybe You have trouble to understand it.

If You want to understand your problem better You need to shrink it to
minimum size,
best if this will be one action, one jsp, and one form.
Then keep in mind that Struts is based on HTTP, that give some restrictions,
and also remember how Struts workflow is done.
Ajax is also based on HTTP and the same restrictions apply.

Then try to describe your problem again,
but before sending it give it to someone else who will read it for You
and check if there is anything thats important.

These all are just general best practises to write a post on mailing list.
Keep in mind that if people doesn't understand your post they simply
tend to skip it,
or if some one like David have more time or more good will they ask
for more details.

At the end, i read your question two times,
and i don't understand what You are trying to achieve,
maybe that's me who is not bright enought,
but that's definitively your problem You want to solve.

Best greetings,
Paweł Wielgus.

[Kawczynski, David]

I believe I understand what you are trying to accomplish:
Ignoring the details (dojo, struts <html:form>, etc) for now... at a
high level, you want to render a page containing a list of items.  You
want to enable a user to get low-level details on any one of those
items.  
So far so good?  
While there are plenty of ways to accomplish this, I don't want to
confuse you further so I'll only cover the simplest scenario:
Assuming each of these items has single unique identifier that can be
used to retrieve the details (your "change number"?) and a single simple
small description that will give the use a clue what that item refers to
(your "description"?)...
 
You want two pages:

*
        one that will render the entire list of items (but only this
simple small description for each item)
*
        one that will render all the low-level details for only one item

 
You want two different DAO methods:

*
        one that retrieves a List of all items' change number and
description.  
*
        one that retrieves one item's details (description, creation
date, user, workspace...) given the item's change number

You want two struts actions:

*
        one that calls the DAO's list method, puts the List into the
httprequest, and renders the list page
*
        one that calls the DAO's details method, puts those details into
a single object and puts that object into the httprequest, and renders
the details page

On the list page: create a <form> whose action points to the struts
details action.  
Create a <select> element, and populate its options from the list in the
http request.  
Make each <option>'s value = the item's change number
Make each <option>'s text = the item's description.
On the details page, render attributes of the details object (found in
the http request).  
 
If you follow this approach, chances are any problem you run into will
be one that can be described in a clear and concise manner.  Once you
get this working correctly, you have the building blocks to do more
advanced things like ajax interactions.  But if you don't have a firm
grasp on the basics you'll only end up frustrating yourself and wasting
a lot your time.  
 
Good luck,
-dave

Thanks for your reply Davidn but please guys try to stop talking to me as if
I'm an idiot stubborn girl who doesn't know what she wants or even what
she's talking about. I'm working with struts for almost 6 months now and I'm
still finding some difficulties not because of my stupidity but because of
the lack of support I've noticed on the web. Either they give you some peace
of code which you don't find a clue how to plug it into your solution or
they just keep turning around your precise requirement to stick with their
struts/java knowledge.

I'm not confused about my requirement sir, I know what I want but the way to
achieve it on struts way is still clueless for me. You've understood one
side of my requirement but you didn't touch my blocking point.

Here is a tutorial I've followed for coding the first part consisting of
rendering a dynamic drop down list with data assembled into a collection
http://www.laliluna.de/download/struts-html-optionscollection-en.pdf

If you got time, check it out and tell me how can I render my description
page into "example" action while it's configured to maintain the business
logic of the data rendered into that drop down list (supposed to be an entry
point and not a resulting page for our form behavior).

I know I'm not good enough in english to explain myself the way it should be
but it hasn't any relationship with my understanding of my requirement and
the logical way to get it done (reaching this state of seeing illogical
things made me wonder how come that no body has encountered such problem
before and how were they submitting their dynamic drop down lists
classicaly).

Regards,
Hanen

Hanen,

I think your response to Dave is outrageous and over-the-top. I didn't
see anything offensive in his email.

> while it's configured to maintain the business logic of the
> data rendered into that drop down list

That example action is a tutorial designed to demonstrate how
the optionsCollection tag works.  It is not meant to be a
starting point for you to develop the functionality you speak
of.  You are trying to do too many things at once.  You need
2 very different pieces of data...
- a list of high-level details
- a group of low-level details
Breaking down the steps allows you to focus your efforts on a
specific issue.  The 2-action class approach I described
allows you to do that.

>(supposed to be an entry point and not a resulting page for
> our form behavior).
This sounds like you want AJAX-like functionality.  If you do
what is described below, enabling AJAX is made easy because
you only have to call details action and render its results
AJAX-style.  

Good luck!
