[jira] Created: (WICKET-2694) Dynamic Form inconsistent behavior
inside/outside a ListView
Dynamic Form inconsistent behavior inside/outside a ListView
------------------------------------------------------------
Key: WICKET-2694
URL: https://issues.apache.org/jira/browse/WICKET-2694
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4.5
Environment: Wicket 1.4.5 , resin-3.1.9 , CentOS 5.4
Reporter: smallufo
The original discuss thread is here :
http://old.nabble.com/Cannot-get-default-invisible-TextField's-ModelObject---td27251305.html
I have a form , which is embedded in a ListView ,
The form contains a radio button.
When user clicks the radio button , a default-invisible textfield is set visible.
But I cannot get the textfield's Model Object , it is null ...
To make it more clear :
When the radio button is clicked , by implement AjaxEventBehavior("onClick")
, a default-invisible WebMarkupContainer is set visible ,
The WebMarkupContainer contains other TextFields , which I cannot get their values at all ....
If the form is not embedded in a ListView , everything works fine .
I think it is an inconsistent behavior and should be fixed.

[jira] Resolved: (WICKET-2694) Dynamic Form inconsistent behavior
inside/outside a ListView
Posted by "Igor Vaynberg (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/WICKET-2694?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Igor Vaynberg resolved WICKET-2694.
-----------------------------------
Resolution: Won't Fix
Assignee: Igor Vaynberg
you are creating invalid markup. you cannot have a <form> tag as a child of <table>. the problem is that the browser is not sending the value of the textfield in the post, nothing we can do about that. interesting that while that is the behavior in firefox, IE does send the value, so your example works untouched there.
my recommendation is to wrap the entire listview in a dummy wicket form, that will make it work since you wont need form tags in the table itself.

[jira] Updated: (WICKET-2694) Dynamic Form inconsistent behavior
inside/outside a ListView
Posted by "Martin Grigorov (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/WICKET-2694?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Martin Grigorov updated WICKET-2694:
------------------------------------
Attachment: wicket-2694.tar.gz
The provided quickstart application and the pasted code doesn't match.
In quickstart app the radioGroup is not a child of the form and thus its getModelObject() always returns false (its initial value).
textfield.getModelObject() always returns the entered value, i.e. it works as expected.
I upload a proper quickstart app because the original one was just few files compressed in an archive.
@smallufo: please revise the new quickstart and update it so it reproduce the problem.

> The original discuss thread is here :
> http://old.nabble.com/Cannot-get-default-invisible-TextField's-ModelObject---td27251305.html
> I have a form , which is embedded in a ListView ,
> The form contains a radio button.
> When user clicks the radio button , a default-invisible textfield is set visible.
> But I cannot get the textfield's Model Object , it is null ...
> To make it more clear :
> When the radio button is clicked , by implement AjaxEventBehavior("onClick")
> , a default-invisible WebMarkupContainer is set visible ,
> The WebMarkupContainer contains other TextFields , which I cannot get their values at all ....
> If the form is not embedded in a ListView , everything works fine .
> I think it is an inconsistent behavior and should be fixed.
