 The collaboration of the processes is then implemented in the handlers. For example, it is possible to get a partner process by name and then send an event to this process. This is frequently done to start the partner process:
 
-	exports.Task_2 = function(data, done) {
-    	// after arriving ot "Task 2" we start process 1
-    	var partnerProcess = this.getParticipantByName("My First Process");
-    	partnerProcess.triggerEvent("Start Event 1");

 However, another option is to get all outgoing message flows and send a message along these flows. In the current example we have exactly one flow, so sending the message is done by:
