Hi Maciej,
Another spot on reply - i'm becoming a fan of yours. I havn't seen the exception in the log after deleting the .ser file.
Once this is done let me bother you little bit more with another harmless exception in my log ... I've used a *com.sample.service.Student* , in my BPMN2 process model. I instantiated this Student class in a script task. For this i needed to upload the jar containing this class as POJO Model in Guvnor. Also this jar is in the jbpm-gwt-console-server.war/WEB-INF/lib. Everything works fine but everytime i login into the jbpm-console, the following exception appears in the server.log. can you please tell me what could be wrong ... do i need to put the jar in the jbpm-gwt-console.war also (but as far i recall i also tried that)?
Thanks
Sumeru
