[jbpm-users] [JBoss jBPM] - Role assignment problem-Task of one user can be accessed by

hi all, I am doing the example given in the ebook "business process management with jboss jbpm". In this eg different roles are assigned to different people,like Talent scout, Legal adviser,Band member etc. When i deployed the process, once talent scout has completed his task and next task is assigned to Legal adviser. But the talent scout is able to start and examine legal advisers task and keep on doing others task. But in real life process it could happen. What I have to do make the tasks role specific. Here is my process definition | | <?xml version="1.0" encoding="UTF-8"?> | | <process-definition | xmlns="urn:jbpm.org:jpdl-3.2" name="Produce music products"> | | <swimlane name="Talent scout"> |
