Hi Daniel,
In order to tell what's going on, it would be good to see some code.
The classes on both sides of the relationship and the code that
changes the relationship are the minimum needed to tell anything...
Except, of course, for the obvious. Have you mapped multiple fields to
the same database column? Have you set both sides of the relationship?
Regards,
Craig

Hi,
I found a error, trying to use a @OneToOne two-sided relation between
objects.
I get this error :
Attempt to set column "TB_SERVICES.CD_USER" to two different values:
(null)"null", (class java.lang.Integer)"55" This can occur when you
fail to
set both sides of a two-sided relation between objects, or when you
map
different fields to the same column, but you do not keep the values
of these
fields in synch.
I tried many things and this is very strange, because this problem
just
occurs with @OneToOne mapping.
Any Clue?
Regards,
Daniel.
