LazyInitializationException after aop configuration

Hello, I recently opened a thread here.

I did because I was getting this exception:

4423 [main] ERROR org.hibernate.LazyInitializationException - failed to lazily initialize a collection of role: path.model.listObjects, no session or session was closed
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: path.model.listObjects, no session or session was closed

So I tried to set up aop (I think succesfully) in my project, to leave Spring the work to open/close the conections with the database. But after that I am getting the same exception. Could it be another reason for that??

The file where I have set up aop configuration is:

Now the explanation:
path.services is the package where the implementations are
path.services.localImpl is the package where the interfaces are


Thanks in advance
