Steve Ebersole commented on HHH-4870:
-------------------------------------

Can you show us the entity where this occurs?  WRT a test case you'd need to pare that down to a minimal test case ( I learned about an awesome resource today : http://www.pscode.org/sscce.html ).  If you are unsure what entity is causing it, crank up logging on "org.hibernate.ejb.metamodel" and you should get pretty detailed logs.

Cross referencing the stack and the code it appears Hibernate is processing a component (what JPA calls an embeddable), if that helps narrow it down.

For some reason in your specific case when we get to http://fisheye.jboss.org/browse/Hibernate/core/trunk/entitymanager/src/main/java/org/hibernate/ejb/metamodel/AttributeFactory.java?r=18609#l589 there is no Member.

> 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.
