Ok I was able to reproduce it. I had two debug breakpoints in Eclipse. One in the submit() method of the session-scope SFSB and one in a @WebRemote demarcated method in the same SFSB for Seam remoting use from a function in a .js file. Both methods were being called in this use case. When I cleared the two breakpoints and restarted JBoss (no code changes) and ran the use case again, the exception did not happen. Is this normal behavior or a bug? thx. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4109403#...
