[jboss-user] [JBoss Seam] - Re: Problem: Custom validate methods in EJBs crash

Well, forget it. There's another problem.

That "complex" validation would work well on an existing person that you edit.

But when you create a new person all its properties are null. And when you fill in the fields in a form and click save, then the persons properties are still null during validation (phase 3). They get their concrete values later, in phase 4 (update model values). And, alas, you cannot compare something to null.

So this is a killer for the idea of validators that should know "more" than just one field.
