AjaxFormSubmitBehavior throws an NullPointerException when getForm() is
overridden
----------------------------------------------------------------------------------
Key: WICKET-2330
URL: https://issues.apache.org/jira/browse/WICKET-2330
Project: Wicket
Issue Type: Bug
Affects Versions: 1.4-RC4
Reporter: Zoltan Luspai
I have an AjaxFormSubmitBehavior where I don't pass the form parameter in the
constructor, but have overridden the getForm() method to find the related form.
(The form is not parent of the button this behavior is attached to, so can not
be found by the behavior itself).
When I "click" on the button attached, the form is submitted nicely, but after
the onSubmit call I get this exception:
java.lang.NullPointerException

Having a look at the source it seems there is a but at this line in
AjaxFormSubmitBehavior:
@Override
protected void onEvent(AjaxRequestTarget target)
{
...
if (form.findParent(Page.class) != null)
...
}
I think that should be :
... getForm().findParent(Page.class)
unless, there is a good reason not to be so?
Btw; I am using wicket version 1.4rc4.
