<div class="jive-rendered-content"><p>I have a simple workflow having a script task, 2 human tasks in succession and then finally another script task.</p><p>Each of the human tasks have a form to be displayed and an approve button. I initially tried the basic process</p><p>without my own task client. It worked but when the actor for the second human task approved the form it came up</p><p>with the following error message. The actor for the first human task is krisv and when he approved the form it went OK.</p><p>But when the actor of the second human task which is john tried to approve his form it gave this exception about krisv</p><p>which did not make any sense he is not at all involved with the second human task.</p><p><span></span></p><pre class="western" style="font-weight: normal;">org.jboss.resteasy.spi.UnhandledException: org.jbpm.task.service.PermissionDeniedException: Server-side Exception: User '[User:'krisv']' does not have permissions to execution operation 'Start' on task id 5</pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><table><tbody><tr><td style=";">  </td><td style=";"><potentialOwner></td></tr><tr><td style=";">    </td><td style=";"><resourceAssignmentExpression></td></tr><tr><td style=";">      </td><td style=";"><formalExpression>krisv</formalExpression></td></tr><tr><td style=";">    </td><td style=";"></resourceAssignmentExpression></td></tr><tr><td style=";">  </td><td style=";"></potentialOwner></td></tr></tbody></table><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><table><tbody><tr><td style=";">  </td><td style=";"><potentialOwner></td></tr><tr><td style=";">    </td><td style=";"><resourceAssignmentExpression></td></tr><tr><td style=";">      </td><td style=";"><formalExpression>john</formalExpression></td></tr><tr><td style=";">    </td><td style=";"></resourceAssignmentExpression></td></tr><tr><td style=";">  </td><td style=";"></potentialOwner></td></tr></tbody></table><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Then I tried creating a Mina task client and processing the task in code. I can get the task, claim, start and complete it.</p><p>But then how do I view the forms and approve it. I have to go back to the JBPM console. Even the human task panel </p><p>in eclipse only allows to start and complete the task. It does not allow to view the forms.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Then I thought let me get the task and claim it in code and do the rest in the JBPM console. I thought the Blocking calls</p><p>will help me do this. But this did not work either. Since the code was consecutive it successively claimed the respective</p><p>tasks for krisv and john. The blocking call did not wait for me complete the operation for krisv through the JBPM console.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am using JBPM5.2. Eclipse Helios SR2, JBoss App Server 7 and I am using the Mina Task Server created by the ant script.</p><p>I have my main process when loads the knowledge base, creates the session, registers the human task handler and starts</p><p>the process. I have my mina client process which creates the Mina task client and does the processing of the tasks.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Your suggestions will be greatly appreciated.</p></div>
