ZK, annotations and GUICE

Hi all.

I was using GUICE to add AOP code to my view controller when I encountered a problem: GUICE automatically generates a proxy object to inject my code and that made ZK unable to find my annotations (@command, @init, etc) anymore.

The problem is caused by the fact that the generated proxy object extends my class, so the annotation should be searched inside the super class.

The ZK BinderImpl class, however, looks for annotation only inside the current class, unless an annotation says that it should matter about superclass: however, as I wrote above, no annotations are found on the proxy object, so the superclass is never checked.

Wouldn't be better to provide a way to ask BinderImpl to check the super class for annotations?

I changed the AbstractAnnotatedMethodInvoker so that the code

curr = (annotation!=null && shouldLookupSuperclass(annotation))? curr.getSuperclass() : null;


// always lookup super classes for annotations...

curr = curr.getSuperclass();

Moreover, I had to create a GuiceBindComposer to substitute the ZK BindComposer to be able to instantiate my ViewModel using GUICE instead of a simple 'newInstance' : wouldn't be better to give the users a chance to declare his own view model factory?

Thanks in advance,
