hmm what I have is this:
@Override
protected void onSelectionChanged(Object newSelection) {
// TODO Auto-generated method stub
super.onSelectionChanged(newSelection);
selectedCategoryNameTranslatable.modelChanged();
dropDownExercise.setModelObject(null);
dropDownExercise.setChoices(((ExerciseCategory)
newSelection)
.getExercises());
dropDownExercise.setVisible(true);
}
it's from an old 1.3 project... So seems similar to what you do..
