Nested forms and conditional validation

2011-03-30 Thread Robert Dahlström 
Hi, I'm currently trying to work out how to do conditional validation 
with nested forms. Googling a bit gave me the following suggestion on 
how to disable a nested form:


(From https://cwiki.apache.org/WICKET/conditional-validation.html)
Form nestedForm = new Form(nestedForm) {
 @Override
  public boolean isEnabled() {
   if (getRootForm().findSubmittingButton() != null) {
return getRootForm().findSubmittingButton().getForm() == this;
   } else {
return true;
   }
}

But when I try this with Wicket 1.4.16 I noticed that 
findSubmittingButton internally calls isEnabledInHierarchy which ends up 
calling isEnabled so I get stuck in a loop that eventually throws an 
exception.


So how should one go about working with nested forms if I don't want the 
nested form to be submitted when the outer form is submitted?


Appreciative of any help,

Regards
Robert

I did manage to get this working using the other pattern from the 
conditional-validation page (i.e. using the FormVisitorParticipant) but 
I'm still curious if the isEnabled solution should work or not?

depending on external factors while overriding isenabled()/isvisible()
is dangerous for the reasons youve just found out.

this is why we take care to provide alternative hooks, such as
IFormVisitorParticipant
