Based on the error message, somewhere in your app there is an EL phrase that uses an object named 'authenticator', but no objects have been marked with that name. (Or perhaps 'authenticator' is being used as a property of an object, but that object has no such property.) If you could locate and post the EL phrase that contains this name, it would help. Also, you might get more help from the Seam forum - that's where the Seam experts hang out (I only know enough Seam to be dangerous). http://www.seamframework.org/Community/Forums View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186068#...
