Hi list:
I've been having a problem with a validation exception that must not

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!
