Why do you have a CompoundPropertyModel with a Model as its generic
type? I would
expect you to want a CompoundPropertyModel.

Given

class ReportWebModel implementsIModel {...}

ReportWebModel reportWebModel = ...;
IModel cpm = new CompoundPropertyModel(reportWebModel);

should succeed, because it matches the CPM constructor:
public class CompoundPropertyModel {
public CompoundPropertyModel(IModel model) {..}
}

Remember, Java Generics have to match exactly.

Re: Wicket 6.5 CompoundPropertyModel constructor ambiguity

Well, from the looks of it it's a bit odd that you write

new CompoundPropertyModel(reportWebModel)

instead of

new CompoundPropertyModel(reportWebModel)

since ReportWebModel extends BaseWebModel

The CPM constructor expects either a type literal or a model. In your 
case it is both, and you tell the CPM (through the generic type) that 
you will provide a type literal.


Does your CPM have to be of type ?

Kind regards,

The problem goes away when I remove the generics but then I also lose the
type checking.

Any suggestions?
