detached object exception thrown when cascade objects are in different PU
-------------------------------------------------------------------------

                 Key: HHH-4082
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4082
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.1
         Environment: Core 3.3.1, MS SQL 2005/2008, Weblogic 10.3, JPA
            Reporter: Lloyd Fernandes


JPA and 2 PUs. All transactions are XA

Jar for PU2 has object process definition which has a collection of process paths and each has a collection of process activities


Jar for PU1 has object workitem that refers to process definition. All PU2 XML hibernate mapping files are imported into PU1 using maaping-file element in persistence.xml


If workitem (in PU1) is read then related process definition, process paths & process activities are read using PU1

A process activity is added, which gets done using PU2

When processing commit/flush a detached object exception is thrown

Caused by: org.hibernate.PersistentObjectException: detached entity passed to persist: mil.army.us.sec.wfm.ProcessActivityDefinition
