      Hi,


      I am currently working with



      • jboss-eap-4.3.0.GA_CP07

      • richfaces 3.3.3.Final

      • jsf 1.2_09-b01-BETA1

      • facelets 1.1.15.B1

      • seam 2.1.2




      Whenever a user hits a button before the page is completely loaded, he is presented a http 500 error page and the following Exception is written to server.log. I've found only this information about that Exception, but that didn't help me. This also occurs sometimes although letting the page some time to finish loading or when uploading a file. what can be done to solve this?
