Re: Wicket page has a redirect loop

2012-06-05 Thread paulstar 
You are right.  I found out the 'markupProvider' is null by debugging, thanks
to Tom to "fores" me to do it.

In Wicket 1.3 & 1.4, I overrided 'getAssociatedMarkupStream(boolean
throwException)' so that the class extends from Fragment doesn't have to
provide 'markupProvider'.  After upgraded to Wicket 1.5, I simply set the
'markupProvider' to null so that it compiled, but ran into NPE.

So I changed my code from:
public static class FormField extends Fragment {
public FormField(String markupId, Component c, IModel label, 
IModel m) {
super("fragmentId", markupId, null, m);
this.labelModel = label;
this.c = c;
}
..
}

to:
public static class FormField extends Fragment {
public FormField(String markupId, Component c, IModel label, 
IModel m,
MarkupContainer markupProvider) {
super("fragmentId", markupId, markupProvider, m);
this.labelModel = label;
this.c = c;
}
..
}

The problem is there are many 'new FormField()' codes, a big changes.

Hi,

I guess 'markupProvider' is null.
This is improved in 1.5.7 to not fail with NPE.
But even in 1.5.7 your app will fail with :
throw new MarkupNotFoundException("No Markup found for Fragment " + markupId +
" in providing markup container " + 
getMarkupProvider(container));

For some reason the Fragment's markup cannot be found. Most probably
you have usage of IComponentResolver near by this Fragment...

Hm, put a breakpoint in FragmentMarkupSourcingStrategy.java:143 and see what 
causes the NullPointerException.
