Igor Vaynberg resolved WICKET-1822.
-----------------------------------
Resolution: Invalid
Assignee: Igor Vaynberg
this change is intentional as it aligns the fileuploadfield componments with
the rest of wicket components - eg they always use their model by default. if
you want to go to the old-style and not use the model then you have to call
sethasexplicitmodel(false).

> Key: WICKET-1822
> URL: https://issues.apache.org/jira/browse/WICKET-1822
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4-M4
> Reporter: Ross Gardler
> Assignee: Igor Vaynberg
>
> This may not be a bug in Wicket 1.4-SNAPSHOT, it may be intended behaviour.
> However, I don't see anything in the migrating wiki site [1], nor do I see
> any recent SVN log messages that make me think it's deliberate (not that I
> understand the nuances of your HEAD work) . Therefore I'm flagging it here
> for you folk can decide if it's a bug.
> If I use 1.4-m3 all my tests pass, if I use 1.4-SNAPSHOT a couple of fail
> (details follow). The change happened between 07-Sep-2008 07:07:25 EST [3]
> and 08-Sep-2008 00:22:04 EST [4] (I can be very narrow on dates as our CI
> server flagged the problem, the first failing build is at [2]).
> The failing tests both give the similar errors (full errors at [5] and [6]:
> org.apache.wicket.WicketRuntimeException: Method onFormSubmitted of interface
> org.apache.wicket.markup.html.form.IFormSubmitListener targeted at component
> [MarkupContainer [Component id = uploadForm, page =

> true]] threw an exception

> So, first question. Is this an intentional change in the way models for forms
> are handled. If so, what do I need to do to make my code work. If it is
> unintentional but you have no idea what is going on then let me know and I'll
> submit some test code to this issue.
