I did some more research and have a theory what is happening: The error message tell us that 'tUser' is not a property of TUserList. When I change the getter to gettUser it is working. So I conclude BeanELResolver just concats 'get' + 'tUser' and does not obey the rules how to map property names to getter/setter methods. The code should uppercase the first letter of the property and then do the concatenation. Does someone know which class is responsible for scanning classes for properties? See the stacktrace for details: SCHWERWIEGEND: Error Rendering View[/home.xhtml] | javax.el.PropertyNotFoundException: The class 'com.seamguru.seamquizadmin.TUserList_$$_javassist_0' does not have the
