Hello

you can add this code in the "complete transition" of your SetUp participant task, or in a conditionnal robot just behind

wt.workflow.engine.WfProcess wfprocess = ((wt.workflow.work.WfAssignedActivity)self.getObject()).getParentProcess();

java.util.Enumeration pinwf = wfprocess.getPrincipals(wt.project.Role.toRole("MY_ROLE_TO_TEST"));

int count = 0;

while (pinwf.hasMoreElements())

{

count = count+1;

pinwf.nextElement();

}

if count==0 no person have been slelected for this role ... so you can route your workflow differently

regards

Gregory

    You can set the "count" as a global workflow variable.

    And then after your setup participant task, put a conditionnal robot.

    If count = 1, route to the next task where the partipant is needed

    If count=0, route to another way with no task for this participant

      Hi all,

      I know it's an oldish thread, but I didn't want to start a new one on the same subject.

      Does anyone have a working example of this code inside a simple workflow? No matter how I try to implement it in WC10.1 M40, it doesn't want to work.

      TIA

      HI Bob,

      I tried to implement the solution with a littlle bit different approach.

      I also have a document for it.

      But i dont know how to how to upload a document.So uploaded the picture of the workflow.

      It may help you.

      Thanks And Regards,

      Kaushik

      Thanks, Kaushik - unfortunately it does help me a great deal!

      The problem is that however I try to implement the code listed in this thread, whether by including it in WorkflowHelper or inside a conditional router, or inside a Complete Transition, I get the following error;

      java.lang.ClassCastException: wt.workflow.engine.WfProcess cannot be cast to wt.workflow.work.WfAssignedActivity

      Nested exception is: java.lang.ClassCastException: wt.workflow.engine.WfProcess cannot be cast to wt.workflow.work.WfAssignedActivity

      What is I'm missing, or doing wrong?

      (None of this helped by the fact that I'm not a programmer!!!)
