shilpa updated HHH-2146:
------------------------

    Attachment: Cascade.java

Hello,

I have attached the  modified org.hibernate.engine.Cascade class which contains the fix to this comment. The sugggested  change has been done to this file at line no. 356. 

eventSource.delete( entityName, orphan, false, null ); 

is replaced with

eventSource.delete( entityName, orphan, false, new HashSet()); 

Could you please commit it to your repository.  

Thanks
shilpa

> The following setup leads to a NPE in DefaultDeleteEventListener.deleteTransientEntity:
> Tables A, B
> Table V_A_B that is an M-N-Connection between A and B.
> Pojo for A has a Set of V_A_Bs.
> Pojo for B has a Set of V_A_Bs.
> Pojo C that has Sets of As and Bs.
> Cascades: all, delete-orphan
> -Create a new A and add a new V_A_B to its Set, that references to an existing B.
> -Delete B.
> -SaveOrUpdate Pojo C.
> In Hibernate 3.1.3 this works fine.
> In 3.2.0cr4+cr5 the removal of B results into an cascading removal of the never persisted V_A_B in the Set of B instead of ignoring it.
> This leads to an incorrect state where deleteTransientEntity is called with transientEnties=null.
> When now calling transientEnties.contains(...) the NPE is thrown.
