Howdy All,
My understanding of relationships that own their related objects in EOF
is that objects are (automatically) deleted (in Java and, as a result
of EOF, from the database) when they are removed from a relationship.
Two questions:
1. How does one move an object from one aggregate to another? Does it
just work, to remove it from one aggregate and add it to another, for
example, in code, or will this cause a problem.
2. If you have a relationship set as "owns destination" *must* the
reverse relationship be mandatory and cascade or deny delete? Optional
and nullify or no-action sound problematic.
Thanks,
Ashley.
