> I've tested to migrate from hibernate 3.3.2 to 3.5.0 Beta4.
> I've remove all hibernate*.jar from classpath and add only de hibernate3.jar
> I've downloaded the source off hibernate-entitymanager to debug from eclipse. I've reached the class that has the error, but I don't know what can I do to resolve it.
> I'm doing something wrong?
> I attatch the sources of the classes that takes part on eclipse debug.
> I don't know how to attach a testcase. The project has more than 200 entities.
> I've post previously in hibernate forums:
