declare a swimlane on the start-task and that will be filled with the actor-id that started the process (presuming you set the actor initially, as does the jbpm web console)

Thx for answer first of all.

I tried such way. But it's not working.

<process-definition xmlns="" name="todo">
 <swimlane name='initiator'>
 <assignment actor-id="#{actor.id}"/>
 </swimlane>

 <start-state name="Start">
 <task name= 'taskforinitiator' swimlane='initiator'/>
 <transition to="UserProcessNum"></transition>
 </start-state>


 <task-node name="todo">
 <task name="todo" description="#{todoList.description}">
 <assignment actor-id="#{actor.id}"/>
 </task>
 <transition to="done"></transition>
 </task-node>

 <decision name="UserProcessNum">
 <handler class="org.jboss.decisiontest.UserProcessNumHandler"> </handler>
 <transition to="todo" name="ok"></transition>
 <transition to="done" name="2much"></transition>
 </decision>


 <end-state name="done"></end-state>


</process-definition>

public class UserProcessNumHandler implements DecisionHandler {
 public String decide(ExecutionContext ec){
String acId = ec.getProcessInstance().getTaskMgmtInstance().getSwimlaneInstance("initiator").getActorId();
 return "ok";

 }
}

And result is...

3. Re: Id of process starter

you cannot have an assignment in it.... just leave it empty and set the actor id with the api on the jbpm context when starting a process

Would You please clear that for me. Do You mean, that I cannot use assignment statement inside swimlane

<swimlane name="initiator">

 <assignment actor-id="#{actor.id}"/>

</swimlane>

or I cannot use swimlane in start task

<start-state name="Start">
 <task name= 'taskforinitiator' swimlane='initiator'/>
 <transition to="UserProcessNum"></transition>
</start-state>

or I should care about injecting Actor instance into JBPMContext before starting the process?

5. Re: Id of process starter

kukeltje Oct 6, 2008 4:20 AM (in response to yozh1k)

not in the swimlane used in thae start task.

Yes, you should set the actor id yourself

6. Re: Id of process starter

yozh1k Oct 10, 2008 4:45 AM (in response to yozh1k)

thx for help =)

Now it's working. But I used processcontext variable instead of swimlane and ActorId...

7. Re: Id of process starter

kukeltje Oct 10, 2008 5:47 AM (in response to yozh1k)

that is a completely different solution, but of course can be done if you want it
