Hello,

I know usually a signal is invoked upon the knowledgeSession, and all processInstances that are registered on this session and listen to the messageType, will be notified. E.g.
ksession.signalEvent("Message-StartProcessMessage", params);


However, how can I signal a specific process instance from within a work Item?

I know how to get to the ProcessInstanceId, but how would I have to go on?

> public class CustomerServiceTaskHandler implements WorkItemHandler {
> 
>     public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
>  System.out.println(workItem.getProcessInstanceId());
> 
>           try{
> ...
>           }catch(Exception ex){
>  myProcessInstance.signal('AbortTheCurrentInstance');
>           }
> 
>     }
> 
>     public void abortWorkItem(WorkItem workItem, WorkItemManager manager) {
>     }
>  }


Best regards,

Tobias
