Description

Current implementation only allows to return a List with the choices for a given property, action or action parameter.

It should be improved to allow to return any descendant of java.util.Collection.

All these cases should be valid:

class Customer {
@SuppressWarnings("unused")
public void someAction(final int x, final long y, final long z) {
}

@SuppressWarnings("unused")
public Collection<Integer> choices0SomeAction()

{ return Collections.emptyList(); }

@SuppressWarnings("unused")
public List<Long> choices1SomeAction() { return Collections.emptyList(); }

@SuppressWarnings("unused")
public Set<Long> choices2SomeAction()

{ return Collections.emptySet(); }

}
