Ah, yes. 1. was a bug indeed. If detaching is too expensive, the model
in question can handle that.

2 things :
1)
In AbstractDetachableModel , the detach() method only detaches the
nested model if ! attached !! that seems odd to me.
I would think that if the nested model exists, it should always be
detached.
So I think its just a simple removal of the else !
2) LoadableDetachableModel
Can getNestedModel() be made non final – since I wish to be able to
build LoadableDetachableModels that have nested models.
For example – in my grid editor – I need to add X null items to the
provided model
protected IModel makeListViewModel(final IModel listModel) {
return new LoadableDetachableModel() {
@Override
public IModel getNestedModel() {
return listModel;
}
@Override
protected Object load() {
List list = (List)listModel.getObject(null);
for (int i = 0; i < 10; i++) {
list.add(null);
}
return list;
}
};
}
I could use a custom Model implementation – however it seems like
this is a natural fit.
