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

Norman Richards commented on JBSEAM-432:
----------------------------------------

I think this is an invalid request.  The only logical place to store unvalidated, uncoverted state is in the view, not the model.   You cannot update the model from a non-validated value.  The UIInput doesn't allow that.  Without completely and fundamentally changing the way input works in JSF, the best we could do would be to somehow turn off the contribution s:validateAll makes, but you would still be left with any other validation (string conversion, required, etc...) and if any of those fail you would not be able to move back to the previous screen. 

Is there perhaps some way to keep the UIViewRoots alive in a pageflow so that the submitted values don't disappear?
