> To duplicate the issue, create three tables in a database with no declared primary or foreign keys.  Map entities to two of the tables.  One of these entities has a primitive @Id; the other has an @EmbeddedId.  Both entities contain an additional field used to join with the third table and populate a collection.
> This works with the entity that has a primitive @Id but for the entity with @EmbeddedId, trying to do anything with the collection after calling the getter results in:
> javax.ejb.EJBException: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of jboss.example.DoesNotWorkPk.id1
>     at org.jboss.ejb3.tx.Ejb3TxPolicy.handleExceptionInOurTx(Ejb3TxPolicy.java:77)
> ....
> Caused by: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of jboss.example.DoesNotWorkPk.id1
>     at org.hibernate.property.DirectPropertyAccessor$DirectGetter.get(DirectPropertyAccessor.java:58)
> ....
> Caused by: java.lang.IllegalArgumentException: Can not set java.lang.String field jboss.example.DoesNotWorkPk.id1 to jboss.example.DoesNotWork
>     at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146)
> I've attached a sample project.  The relevant files are Works.java, DoesNotWork.java, and DoesNotWorkPk.java
> There's also data.sql along with the java files to populate a mysql db, but I think any DB will do.
