[jboss-user] [JBoss Seam] - exception

Sat Aug 18 06:40:31 EDT 2007

In a page with only a h:outputText and a h:form, as soon as I click on the submit button of the form, I get this exception

It must be obvious but i have no idea why. 

The application is generated with seam2/seam-gen from today cvs. The only changes are:
- outputText and form in home.xhtml
- class BindingTest.java
