Hi,
Looks more like an issue with your criteria. Have you tried to use
FetchMode.EAGER instead?

Hi all,
I have a little problem.
I'm using hibernate criteria to fetch list of objects that I want to display
in loop component. (enclosed in my commentModule component)
Criteria criteria = getManager().createCriteria(CommentBean.class);
criteria.setFetchMode("user",FetchMode.JOIN);
this criteria should return list of commentBean objects and associated user
object (as said in hibernate documentation),
BUT
when i call in loop element comment.user.username to optain username of user
that posted comment I get this error:
Render queue error in Expansion[PropBinding[expansion
collaborators/Details:commentsmodule(comment.user.username)]]: Property
'user' (within property expression 'comment.user.username', of
me.xxx.xxx.components.commentsmod...@eaabad) is null.
I tried all sorts of thing but I'm not sure what to do next... Is this
problem with tapestry and is there some sort of work around?
