Any new on this one? We use JBoss Portal with JSF Portlets. The exception occur everytime a user double clicks a button or actionlink (ex. clicking on an actionlink before the first click has been handled). I'll expect that the first click will be cancelled and the second will start being handled, but instead a ServletException "Stream Closed" i thrown. Any ideas?
