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.

> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.5
> Environment: Wicket 1.4.5 , resin-3.1.9 , CentOS 5.4

> 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.
