I have a PapelEntity class that has many-to-many relationship with the CompetenciaEntity.
The problem can be seen in the method initialize collection is as initilized. And the log shows the collection as uninitialized. So, when the object gets in the client app, I get a LazyInitializationException
A very important thing, this functioned very well with hibernate 2.1.8
Somebody knows what it can be happening? To upgrade the version of hibernate 2,1,8 to 3.1 did I miss something?
Excuse my bad english :P
Hibernate version: 3.1 beta 3
