the code:

       public void removeInconsistencyFromItem(EaiItem item)
        {
                Inconsistency inc;
                
                if(null!=(inc=item.getInconsistency()))
                {
                        item.setInconsistency(null);
                        inc.getEaiItems().remove(item);                 
                        
                        if(inc.getEaiItems().size()==0)
                        {
                                // following line causes the exception:
                                entityManager.remove(inc);
                        }
                }
        }

i think the probem is described here: (JBSEAM-2983), but i'm not sure how to react. How do i have to define my hibernate entity?

thx for advice
