Wow ... there´s a warning about this post beeing old but ... I guess I´m pretty sure to reply.
Ok, to the question. In my code I do something like this.
...
facade.registerMediator( new UsersListMediator( new UsersList() ) );
...
So, everything changes on the UsersListMediator. Should I use the Container initialize() method or FlexEvent.CREATION_COMPLETE?
I can be more specific if that wasn´t clear enought.
Thansk!
