and how a component can get to know the page in which it is included? I
mean, I can't @InjectPage, as the component will be included in many kinds
of pages.
@Kristian: thx for the many ways :) I'll try these, hope that the
@Environmental stuff is scalable (I'm trying to bypass session creation as
much as possible)
Is there a doc on the various annotations available?
@Michael:
Could you include a tiny bit of example? THX!
Thx to you all
cheers
