Strange Exception

[xinhua]

Hi,all
Sometime, a very strange exception will occur (at least for me it is:P) when i QUICKLY double click a Statefull SB supported link

Caused by javax.el.ELException with message: "javax.ejb.ConcurrentAccessException: no concurrent calls on stateful bean 'jboss.j2ee:service=EJB3,name=TestPage2Bean' (EJB3 4.3.13)"

What does it mean?
thanks.

Try upgrading to a newer version of Seam, we fixed this problem there.
