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

[CptnKirk]

I agree with Gavin.  I've always been ok with complex validation in the action method (or control flow).  If you need something a little more declarative, it shouldn't be too hard to use Seam plus EJB interceptors to write your thin framework.

If you think about it this is what JSF is doing anyway with its phased approach to conversion and validation.  Being able to use EJB 3 allows you to slip in your own layer immediately preceeding action invocation.  You'd then be able to apply any declarative application concerns, including validation, on objects that had already been converted and validated in isolation.

Would it help if Seam provided a "standard" annotation that highlights this ability or should users just implement something like this on their own?  I guess if this feature is being requested, giving the masses what they want may have some value, even if it's just providing a utility that they could provide themselves.  Utility is a good thing.
