Jacob DuBray updated WICKET-1894:
---------------------------------
Attachment: Quickstart.zip
I mentioned the observation of this issue in 1.4.7 as noted in
http://apache-wicket.1842946.n4.nabble.com/AjaxFallbackButton-onSubmit-call-order-td2067805.html#a2067805
I recently checked back to see if a newer release contained a solution and
noticed it was closed without a fix version. It directly affects usage of
deferred validation in a form's onSubmit method when an updated model object is
required for further validation. I could get into more detail with my
particular need for this usage, but that's not necessary to illustrate the
problem.
I've attached a quick start illustrating the problem in 1.4.12. Is this still
an issue or has it been addressed in some other issue or change in 1.5?
Thanks

> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.5, 1.4.7

>
> I just stumbled upon a problem with a Form containing a nested Form and two
> AjaxFallbackButtons (submit and preview). I need to implement different
> onSubmit() behavior of the nested Form depending on the clicked button.
> The order of onSubmit() calls is:
> without JS:
> - AjaxFallbackButton.onSubmit(AjaxRequestTarget,Form)
> - OuterForm.onSubmit() // not used
> - Inner Form.onSubmit()
> with JS:
> - Inner Form.onSubmit()
> - OuterForm.onSubmit() // not used
> - AjaxFallbackButton.onSubmit(AjaxRequestTarget,Form)
> With JS, it is therefore not possible to determine which button was clicked
> from inside a form's onSubmit() method.
