I read that the HbResourceImpl replaces the HibernateResource in case
that I want to close the session each time.
I changed my code to use the HbResourceImpl, but it does not support
lazy loading.

Does any one knows how to fix this?
Sample code or new version? (i'm using 0.8.0)

Thanks
Yigal

Hi Yigal,
To be honest, this resource implementation is not used very often (afaik). What happens with your
lazy loaded lists, do you get an exception or is everything eagerly loaded?

Why not use the standard HibernateResource?

When the lazy load for the list is activated, it calls a method called
getSessionWrapper from the HbResourceImpl. This method is not
implemented and returns a null that causes a null exception

Can you enter a bugzilla for this then I can look at it? I am not sure if it solves your issue though.
