- Display1 to Chat2 - Route4
Figure 1: Event Process set as per scenario
As per In the above connections, when the Event Process is launched , if and a message is sent from the Chat1 component, it is received by the Display component and the message is sent back to both Chat1 and Chat2 components from the Display output port.
Now, define Define conditional data flow from the Display component instance by assuming that Display1 has to send only those messages on Route3 which are sent from Chat1. Similar conditions should also apply to route4 so that it should allow allows only those messages that is sent from chat2 to Display1.
