My mapping are ok, because yesterday I used eager fetching on all collections
and it worked, I just removed every eager mappings and create criteria for
all one level criteria, problem is when I try to go deeper...
It seams that problem is that session is closed when I try to fetch data...
It seeams that tapestry is closing hibernate sessions automatically.
Someone told me to implement open session in view... Any suggestion about
that matter?
Tnx for your fast answers :)
