You probably have Propagate Primary Key set on this relationship. If
the relationship is to-one and Propagate Primary Key is set, EOF will
automatically create the object that is the destination of the
relationship. You then create it again in your code, but the object
that EOF created is still in the editing context, will all null values.

I'm using two tables(master-detail), the master is inserted in the
EC when the component is loaded, then you can add details, the
details are only created and inserted in the EC if the variables
holding the values pass some validations(same validations are
implemented in validateXXX methods in EO class), one of the
validations is the one that is being thrown in saveChanges(). I've
no idea of what I'm doing wrong. If you need a copy of the code and
the component please let me now. I'll appreciate any help.
Thanks in advanced!
