Well, if I annotate a private field with, say, @Length(max=50) and validate a form, invalid data doesn't get flagged. But when I move the same annotation to the corresponding property getter, validation works perfectly. Hmm... I wonder if it has anything to do with my naming convention for private fields. I use an "m_" prefix. Maybe this prevents Seam from determining the property name. Is there a Seam equivalent to Hibernate's NamingStrategy interface, so I could tell it how to translate field names to property names?
