Hello I have a running project that when I replace the files : jboss-seam.jar,jboss-seam-ui.jar of version 1.0.1GA with the one that come with version 1.1.0GA I get the error "Illegal use of @Table in a subclass of a SINGLE_TABLE hierarchy: <name of class B>" In my project Class B extends another class A and they both share the same mySQL table. I am doing it using the @Table annotation As a result the project fails to deploy because "Two components with the same name and precedence" Again with seam 1.0.1 everything is working....
