> 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.
