[OJB-developers] Bug in M-N relationships

[Matthew B. <ma...@so...>]

Given the following database tables
USER
USER_ROLE
ROLE

and the objects
User
Role

if I create a relationship in the objects by adding a user to a role, then
make it persistent, everything is ok.

if, after I create one relationship, create a new user and add him to the
role and persist it, the relationship record in USER_ROLE that existed for
the first relationship gets multiplied by 3. Then if I do it again, it gets
multiplied by 3 again. This could quickly get out of control.

Can anyone confirm this behaviour?
