Problem with <parent> for 2+ levels of components
-------------------------------------------------

         Key: HHH-2459
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2459
     Project: Hibernate3
        Type: Bug

  Components: core  
    Versions: 3.2.2    
 Environment: Hibernate 3.2.2, Tested on PostgreSQL and HSQL
    Reporter: Kevin Bragh
 Attachments: test.zip

I have tested several scenarios similar to the above, and I have searched and posted to the forum with no response.
I have attached the faulty code to the thread.


I have a main class (A) with 3 components recusively included as follows:
A -> B -> C <-> D

In the case above, D has a <parent> property to C.

While loading an instance of A, it seems that D.setC(...) is called with the value of the main class A, and not of parent C.

I don't know if this is a bug, or if parent is not recusively supported.

Any help is appreciated.

Thks, K.

NB: I have tried many different examples (with list and composite-element, etc.) and they all fail with 2+ levels of recursion.
