Hi clement! Well, so maybe you could give me a hint.
Is there any way to know when all the components of a custom handler of a specific bundle has been instantiated and activated? For example, a bundle X defines components A and B wit a custom handler NS:H. Components A and B are all immediate annotated with @Instantiate. So, how can I know when iPojo finishes processing bundle X? I tried listening to Bundle.STARTED event, but it seems that ipojo processing is happening after this event (or it's async, I don't know). Any help apreciated!
