[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-432) Support @IfInvalid functionality without @IfInvalid

Gavin King commented on JBSEAM-432:
-----------------------------------

Y'know what I think is the best way to handle this: just have an API that you can call from an action method to validate the model. Let you attach the messages to the form field yourself. That gives complete control for all these crazy cases, I guess.
