I think we could move the wrap up:
setId(id);
this.model = wrap(model);
getApplication().notifyComponentInstantiationListeners(this);
I can't really think of anything that would go wrong because of that
(wrap is final), and it doesn't result in test failures or does it
cause anything to go wrong with the app I'm working on. So I committed
this change.
Hope that helps you.
