This was 'discussed' recently:

I don't remember a Jira issue being created though.

Hi all !
I have a nested form inside a root one, both are multipart. I want to cutomize
the onFileUploadException(..) method of the nested form in order to trace this
event. So I overrided the method of my nested form instance, typically to get a
trace of file size limit exceeded.
But Wicket calls the onFileUploadException(..) on the root form, not on the
nested one, so my overrided code doesn't apply.
I found that it's due to the AjaxformSubmitBehavior which calls
onFormSubmitted(..) on the root form, here's the code :
protected void onEvent(final AjaxRequestTarget target)
{
getForm().getRootForm().onFormSubmitted(new
IAfterFormSubmitter()
{
...
So I used my own behavior with the modified line (getRootForm() removed) :
getForm().onFormSubmitted(new IAfterFormSubmitter()
and it works : the onFileUploadException(..) of the nested form is called, not
this of the root form.
I couldn't find another way to make it work, did I miss something ?
I think that Wicket should call onFileUploadException(..) on its nested forms
so I think the actual behavior is a bug, am I wrong ? (I can fill in a bug if
necessary)
I'm using Wicket 1.5.10.
Thanks !
