Re: Cannot get default invisible TextField's ModelObject ?

[Chuck Brinkman]

I looked some more and found the following:

When it works, with my modification, FormComponent.getInputAsArray tries to
get parameters for the TextField named "more:moreForm:textfield".  I looked
in the parameter map or the RequestFacade object and found these:
wicket:interface, wicket:ignoreIfNotActive, random, more:moreForm:textfield,
radioGroup and more:moreForm:submit.  And it finds the TextField.

The version that fails is looking for TextField named "more:textfield".  The
RequestFacade object has: wicket:interface, wicket:ignoreIfNotActive,
random, forma_hf_0, radioGroup and more:submit.  Is there a problem with
"forma_hf_0?

Re: Cannot get default invisible TextField's ModelObject ?

[smallufo]

Yes , indeed , if the form is in the second row (default invisible) , it
works , But I cannot get the first row's data (such as radioGroup's model
object will become null ).
Moreover ,  Form with multiple row , with something visible and something
extensible (default invisible), it is not so rare.
If the form is not inside a ListView , it will work.
But it just fails if it is inside a  ListView.

Re: Cannot get default invisible TextField's ModelObject ?

[Chuck Brinkman]

I stepped through the code and found that the convertedInput is null when
processing submit.  I didn't see anything that looked like an error message
from wicket.I look forward to seeing what the wicket developers have to
say.

I'm just a new wicket user but was interested in this issue.  I also found
that if you make the following changes it will work.
   

**


   * *




*Form moreForm = new Form("moreForm");
more.add(moreForm);*
final TextField textfield = new TextField(
"textfield", new Model());
*moreForm*.add(textfield);
AjaxButton button = new AjaxButton("submit") {
@Override
protected void onSubmit(AjaxRequestTarget arg0, Form
form) {
System.out.println("radioGroup = "
+ radioGroup.getModelObject()
+ " , textfield.getModelObject() = "
+ textfield.getModelObject());
}
};
*moreForm*.add(button);

Re: Cannot get default invisible TextField's ModelObject ?

This is a full functional Page  :

I found this problem only occurs when the form is in the listView :
If I move the form out of the listView , it works like a charm.
Bug ? I am not sure...

Re: Cannot get default invisible TextField's ModelObject ?

[Jered Myers]

What do you mean by "cannot get their values"?  I am wondering if the 
model's value is not showing in the TextField when it become visible or 
if the model's value is not getting set based on what you type into the 
TextField.  If your problem is that the value you type into the 
TextField is not getting to the model, check to make sure the Form that 
the TextField is in is reaching the Form's onSubmit method when you 
submit the form.  Wicket does not push the TextField value to the model 
until it has checked for required fields, converted the input, and 
validated the converted input.  If you can copy in the related code to 
this thread, that may help.

I have a form , which 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 

What's the problem ? Did I miss anything ?

Cannot get default invisible TextField's ModelObject ?

[smallufo]

I have a form , which 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 

What's the problem ? Did I miss anything ?
