------------------------------------

Gail,

I'm facing the same problem as CHILLAN reported. Is there another way to discovery the node "name" of a collection inside the "onPostRecreateCollection" of PostCollectionRecreateEventListener?

Inside the "onPostRemoveCollection" of PostCollectionRemoveEventListener everything is fine and I can get the node with no problem.

The code in the "onPostRecreateCollection" method wich I have problem is

     public void onPostRecreateCollection(PostCollectionRecreateEvent e) {

                .....
		Collection c = hibernateConfiguration.getCollectionMapping(e.getCollection().getRole());
		Table t = c.getCollectionTable();
		System.out.println("Tabela: " + t.getName());
		
		Iterator it = e.getCollection().entries(e.getSession().getFactory().getCollectionPersister(e.getCollection().getRole()));
		
		for (;it.hasNext();) {
			System.out.println("Removendo... " + it.next().toString());
		}
		........
		
		
	}

The "e.getCollection().getRole()" call returns null.

Thanks

>   // during flush shouldn't be ignored
>   ignore = false;
>   collection.clearDirty(); //a newly wrapped collection is NOT dirty (or we get unnecessary version updates)
>   snapshot = persister.isMutable() ?  collection.getSnapshot(persister) : null;
>   // -- ADDED LINE HERE --
>   role = persister.getRole();
>   collection.setSnapshot(loadedKey, role, snapshot);
