Honeycomb currently stores conversation state, especially the Hibernate session, in a Tapestry ASO rather than directly in the session. Therefore it's inaccessible outside Tapestry.
You have basically two options: - replace you Servlet Filter with a custom Tapestry-Service - override the ConversationManager, so that it directly relies on the Http-Session. You'd need some kind of Filter wiring the ConversationManager to the Session then. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: Monday, June 18, 2007 7:34 PM > To: user@hivemind.apache.org > Subject: RE: Acquiring session not in a tapestry page error > > Hi! > I have a similar problem and I can't find the answer to my > problem for now.
