Esko Suomi commented on WICKET-2479:
------------------------------------
Interesting side effect I just noticed: Clearing another datetimefield
invalidates current session.
> NPE when clearing DateTimeField
> -------------------------------
>
> Key: WICKET-2479
> URL: https://issues.apache.org/jira/browse/WICKET-2479
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 1.4.1
> Reporter: Esko Suomi
> Priority: Blocker
>
> This bug is apparently caused by regression of some sort since this was fixed
> for 1.4.0 (see links below). Simply, the NPE still occurs when clearing the
> DateTimeField. In our environment we're using CompoundPropertyModel as model
> object for the related form. When I get back to work (it's saturday so that'd
> be a few days) I can paste the stacktrace but I doubt that's needed, this
> should be easy to fix based on information in the previous issues.
> Since fixing of this bug has obviously failed before, I've set the priority
> of this one to Blocker to enforce its quick resolution.
