Re: Hibernate problem with OGNL
Hi, I think I've found the problem. I had javassist 3.17.1 (latest) in my project but hibernate 4.2 ships with version 3.15.0 Now it seems to work! Thank you, and sorry for misplacing my question here!

You know, HHH uses all that magic with proxies, baytecode manipulation
and so ;-)

Hibernate problem with OGNL
Hi,
I don't know if this is the right place to ask, but maybe there is
anyone who has experienced the same problem.
I'm using Struts2 (latest version), with Hibernate (latest version)
My database models all have getId().
I have situations, where the getId() method of my model class returns
null when navigating through OGNL e.g. when
calling .
When I call getId() from the method in my action class (e.g.
UserListAction iterating though users and calling
user.getGallery().getId()), it returns the id as expected.
If I do that first in my action class, then also my
renders the id as expected; so I thought about a lazy loading issue...
all my getId() methods are public, NOT final, and the Long id members
are protected.
I also tried to add a getMyId() method in the model which calls getId()
from within the same class.
getMyId() { return getId(); }
This surprisingly works and outputs the correct id when calling
Did anyone experience something simliar or has any suggestions?
OGNL 3.0.6, Hibernate 4.2, Struts 2.3.12
Thanks,
Markus
