Hi Michael, Due to the change to the Unified EL from MyFaces 1.1 to 1.2 some EL related things changed. The problem you're describing is one of those, I'm afraid.
Looking at the first item in the stacktrace you can see that the Exception does not come from MyFaces, but from tomcat's implementation of the Unified EL: org.apache.jasper.el.JspValueExpression. You can workaround this by moving the logic to a managed bean property.
