Hello Grokkers,

Well, I'd appreciate ANY opinions and reactions on this.
This is an important matter an it has to be discussed.

> that the content created by his subscriber won't be cataloged, nor
> added to the IntIds utility, etc...
> This situation is very annoying, since the creation of content as the
> site creation is a fairly common usecase (yes... one of mine, you've
> got it). I propose the creation of a new event we could call
> ApplicationInitializedEvent, for instance, and that would be fired
> AFTER the ObjectCreatedEvent. This would permit a more flexible

> persisted, ready to be used. Obviously, this can't be plugged in
> grokui.base, it belongs to Grok itself. What do you guys think ?
