Try the set… method then.  Also check the relationships to this entity in the 
model.  Is one set to Nullify?  It could be EOF doing this as part of a save.

Hi List,

I am trying to pin down where a to-one relationship is getting set to null 
inappropriately.

I added validateMyRelationship() to trap and throw and this is triggered ok 
when the base object is created / updated.

However, it wasn't called when the relationship was set to null and hence the 
update proceeded, bypassing my trap.

Does the above scenario ring any bells; why isn't validateMyRelationship() 
called when I can see the update request to the database follows.

I can't set the relationship to mandatory as in some circumstances null is 
valid, though it should never change to null after it has been set.

Thanks
John
