Re: Tapestry - hibernate problem

[Nicolas Bouillon]

Hi,




Best thing to do is to run your Criteria in a JUnit test.

You should check your mapping to be sure the many-to-one relationship between "comment" and "user" is correct, and verify your database table "comment" contains an existing foreign key to the user table.

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?
