ok
onexception is for exceptions that occur during form processing. in
onsubmit() you are responsible to process your own exceptions since that is
your own handler code

Something like the following code:
Button searchButton = *new* Button("searchButton",
*new*StringResourceModel(
"searchButton", *this*, *null*));
searchButton.add(*new* MyAjaxFormSubmitBehaviorWithIndicator(form,
"onclick") {
*protected* *void* onError(AjaxRequestTarget arg0) {
*super*.onError(arg0);
}
*public* *void* onException(Component target, RuntimeException
e) { ß Does not get called
*super*.onException(target, e);
}
*protected* *void* onSubmit(AjaxRequestTarget target)
{
Collection ldapUsers = getUsersOrGroupsFromLdap() ß causes
a null pointer exception
target.addComponent(*this*);
}
}
So in the following code, AbstractBehavior.onException does not get
called, and it is also not being handled by RequestCycle.onRuntimException,
since I have overridden that to catch run time exceptions already, I know it
is not being called. This is making it rather difficult to implement ajax
error handling for this situation.
Alternatively, I have a similar piece of code where I explicitly do a
'throw new MyRuntimeException()', and this DOES get handled by
RequestCycle.onRuntimeException.
Any ideas?
Thanks

Hey guys,
When I have an exception (in this case a NullPointerException) occur
during the onSubmit of an AjaxFormSubmitBehavior, neither onException or
onError is being called. Why is that? I thought these methods existed
specifically to catch these types of problems?
Thanks
