------------------------------------
Hi!
I still get this kind of 'blind' exception not displaying the 'expression' that
is related to the cause:

> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 1.4-M3
> Reporter: Martin Makundi
> Assignee: Johan Compagner
> Fix For: 1.3.5, 1.4-RC1

> Original Estimate: 1h

> WicketMessage: no set method defined for value: true on object: ...
> at
> org.apache.wicket.util.lang.PropertyResolver$MethodGetAndSet.setValue(PropertyResolver.java:1107)
> In case there is a getter method defined, it would significantly help
> debugging to display the get method name in the exception.
> I suggest fixing the problem with:
> - " on object: " + object);
> + " on object: " + object + " while
> respective getMethod being " + getMethod.getName());
