Filter notifications when resource is loading [message #988705]

I'm trying to create an adapter for certain models of EMF Eclipse that must capture the "add" notifications. What it should do is that when I add something to the model must show a dialog asking some questions.

However when I open the model, I'm receving lots of add notifications. I suppose that it's normal, because when you open a model it must load all its features and emf must add them to the in memory model (or something similar, I'm a newbie in emf).

But that's a serious problem because I don't know what "add notifications" are coming from the model loading or from an interaction of the user.

Is it possible to make a filter to skip all the notifications coming from the load of the model?

Thanks a lot!

Aarón,

How are the adapters attached? You should consider attaching them in
response to the Resource.RESOURCE__IS_LOADED notification much like
org.eclipse.emf.ecore.change.util.ChangeRecorder.notifyChanged(Notification)
does. You can also guard with
((Resource.Internal)eObject.eResource()).isLoading().
