    javax.ejb.ConcurrentAccessException

    Patrick Madden Newbie

      Hi,

      I'm getting an error sometimes on a page that uses a Seam Component with Application Scope. I have a page with RichFaces Tab component with two tabs each of which contains a table. I'm using a4j:poll on this page to auto refresh my tables. Occasionally I get the following exception :

      Caused by: javax.ejb.ConcurrentAccessException: no concurrent calls on stateful bean 'jboss.j2ee:service=EJB3,name=EnterpriseGridBean' (EJB3 4.3.13)

      15:35:44,009 WARN [lifecycle] executePhase(RENDER_RESPONSE 6,com.sun.faces.context.FacesContextImpl@be1ab9) threw exception

      Anyone have any ideas. I can't seem to find much on this error.

      I'm using JBoss 4.2.1.GA and Seam 2.0.CR1 and a very recent snapshot of RichFaces

      Thanks in advance.

      PVM
