problem with updateCollectionReferences

Hi Allessandro, Hi Ng,

it seems to me, that an object with a lot of collections and many other 
objects will not be saved right into the db.
If i remove something from the collection tree of this object, it will 
not be removed from the db.
The object tree is very nested...
I have debug everything of my object -  it will be give right to 
mandragora - but the delted things will not be deleted in the database.

Is there something, what i can do, or is the only solution, to save the 
things "by hand" or single ?
