 "Not an entity class" error upon migrating to 2.0.0 GA
 ------------------------------------------------------

                 Key: JBSEAM-2220
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2220
             Project: JBoss Seam
          Issue Type: Bug
    Affects Versions: 2.0.0.GA
         Environment: Linux, glassfish v2, postgresql 8.x
            Reporter: Levent Aksu

 I migrated my application which was running previously with 1.2.1 GA. It starts and works
nicely till it gets to the first "insert" with the following stack trace:
 Hibernate: select nextval ('hibernate_sequence')
 java.lang.IllegalArgumentException: Not an entity class:

 Note that "Category" is a mapped class and previously in the log I can read
those lines:
 ...
 Mapping class: datassist.payroll.entity.Item -> Item
 Mapping union-subclass: datassist.payroll.entity.Category -> Category
 Mapping union-subclass: datassist.payroll.entity.Unit -> Unit
