Hi Linda,
You are assuming that
IModel<List<Subgenre>>
is a subtype of
IModel<List<? extends DomainObject>>
In java this is not the case (even if Subgenre extends DomainObject).
You'll need an explicit cast to make this work:
IModel<List<? extends DomainObject>> castedModel =
(IModel<List<? extends DomainObject>>) subgenreModel;
Regards,
Erik.

This is not really Wicket related, but I don't quite know where else
to ask this. The question is: why won't this compile?
// I define a model
IModel<List<Subgenre>> subgenreModel = new
AbstractReadOnlyModel<List<Subgenre>>() {
...
}
// Here I try to use the model
FieldSwitchPanel subgenrefield = *new
SubgenreFieldSwitchPanel("subgenre", subgenreModel);*
// This is the constructor for the class SubgenreFieldSwithcPanel
public SubgenreFieldSwitchPanel(String id, IModel<List<? extends
DomainObject>> choices) {
...
}
// Subgenre extends DomainObject
public class Subgenre extends DomainObject{
...
}
The complaint is: The constructor SubgenreFieldSwitchPanel(String,
IModel<List<Subgenre>>) is undefined.
Thanks,
Linda
