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

[Christian Bauer (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBSEAM-432?page=comments#action_12348900 ] 
            
Christian Bauer commented on JBSEAM-432:
----------------------------------------

BTW, my first approach (which is in the new Hibernate book as well) was to defer model validation (not until flush/commit time, but until Next Page is clicked) with @IfInvalid and without <s:validateAll>.
