Hi ,

    When i use the signal to handle the exception , i found there is only one attr 'SignalRef' to identify the signal , but when there are several instances running at the same time , it's hard to handle it separately . What i mean if we use the api to trigger the signal 

kcontext.getKnowledgeRuntime().signalEvent(eventType, data, kcontext.getProcessInstance().getId());

,  we can declare the instance id , but how can we do it when we use signal ?

Thanks !
