Seam error after upgrading to richfaces 3.1.2

[mgrouch]

After upgrading to richfaces 3.1.2 we started getting this exception:
(We use Seam 1.2.1.GA from JBoss EAP 4.2)

javax.el.ELException: /login.xhtml: Property 'login' not found on type org.jboss.seam.security.RuleBasedIdentity

How can we fix it?
Thanks

This normally means facelets is trying to interpret the methodbinding as a valuebinding because, for some reason, the tag is being processed properly. Do you have the JSF control with #{identity.login} commented out? Or perhaps the RF library is no longer being loaded, so the tag is processed as straight XML. Check the app load to see if this is the case.
