Hello Aleksej,

Since I am not a Tapestry user, please take my answer with great care;-)
As far as I understand the problem you describe, it seems that Tapestry, on
refresh, uses a cached page, I believe that your page stores your persistent
object (loaded on first page display). The -potential- problem in this case
is that the object is not attached to any Hibernate session any more.

Maybe what you are looking for is the "long conversation" pattern of
Hibernate. However, HiveTranse does not (yet) implement this pattern (and
will not do in the short run because I am more than busy currently).

You have 2 possible solutions (out of the scope of HiveTranse but more in
the scope of usage patterns of Hibernate):
1/ Use another framework for Hibernate integration in HiveMind/Tapestry (I
know there is at least one such framework that supports "long conversation"
pattern, I'll let the "parents" of these frameworks complement my answer).
2/ Go on with HiveTranse, but make sure your persistent object, as stored in
your page, is reattached to a new Hibernate session (see Hibernate API) that
will be again provided by HiveTranse.

Hope this will give you some useful hints.

Cheers

Jean-Francois

Subject: Hivetranse: BUG or incorrect usage of DeferSessionClose?

In my application I need to allow Lazy initialization.
I am using hibernate3 and Hivetranse.
Property 'hivetranse.hibernate3.DeferSessionClose' is set to 'true'.
When I first time viewing page where lazy access to object property is used
everything works fine. ( With DeferSessionClose turned to false I got 
LazyInitializationException ).
But if I refresh this page then I got LazyInitializationException too. 
Later I found  that if I will
prevent Tapestry to create another one instance of the page in the pool 
( making lots of request at one time )
 then that new page will be viewed OK. It looks like a BUG but I am not 
sure.
