Hi list: I've been having a problem with a validation exception that must not be happening, here is the stack trace:

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!
