Message wait and notification in OBPM

The exp file is under Avio-OBPM Training\Message Wait\

Parent/Child Notification using Send Message Activity

In task 1, this is sending notification from the child process.

Add a “Message wait” event, in its properties window

The first dropdown list is the name of the activity that invokes the subprocess. In this example, the process “SubProcess” invokes the subprocess.

The radio of “Waits for” indicates that it would be notified by a Child process.

create argument “customerStatusArg”

Add argument mapping

In the subprocess, put in the “Send Message” event

set the argument mapping

In the “Child Process before the Notification”, it already contains the code. Here it has an example about populating dropdown list at runtime.

input "Customer Status" : customerStatus in ["Active","Inactive","Pending"]
    using title = "Enter customer status", 
          buttons = ["Ok", "Cancel"]
    returning selectedButton = selection

External Notification

task 2, this is to send notification from another process (not child process)

Add a “Message Wait” event,

Select the “external” radio.

Add argument and its mapping on “Message Wait” event.

Double click the “Begin” activity in the “Process to Notify Externally” process. Note that a mapping has already been created for you. “id.id” is predefined variable.

This will display the id in column description on the screen.

In Process “Sender of Notification”, double click “Sender of Notification”. And put in this code. This is the code in PBL

instanceIdToNotify as String
selectedButton as String
customerStatus as String

// Associative array to pass with notification
params as Any[String]

input "Enter the instance id to notify" : instanceIdToNotify (textarea) ,
	   "Enter the customer’s status" : customerStatus
    using title = "External Notification", 
          buttons = ["Ok", "Cancel"]
    returning selectedButton = selection

params["customerStatusArg"] = customerStatus
     
// Pass in the id.id of the instance to notify and the 
//  name of the activity it is waiting in
send Notification
    using instanceId = instanceIdToNotify, 
          activityName = "MessageWaitHitExternally", 
          argumentSetName = "In", 
          parameters = params

Here is the same function in java

String instanceIdToNotify;
String selectedButton;
String customerStatus;

// Associative array to pass with notification
Any[String] params;

input("Enter the instance id to notify" instanceIdToNotify (textarea),
      "Enter the customer’s status" customerStatus, title : "External Notification", 
buttons : { "Ok", "Cancel" }, out selection : selectedButton);

params["customerStatusArg"] = customerStatus;

// Pass in the id.id of the instance to notify and the 
//  name of the activity it is waiting in
Notification.send(instanceId : instanceIdToNotify, activityName : "MessageWaitHitExternally", 
                  argumentSetName : "In", parameters : params);

When testing, copy the “id” from the description and paste it.

 

Notification with an interrupt

task 3, this task will be able to send notification to a process and interrupt it. For example, cancel an order.

 

Select “External” and “Allows interruptions”, the Message Wait activity is an orphan outside of the process flow. It has no transitions coming into it. It has a lightning bolt inside of it. The bolt indicates that it allows interruption in the process.

Create a Interactive activity

Put in this code

customerStatus = "Interrupted"

action = BACK

To test it

Click “After the interrupt”, because of the code “action=BACK”, it sends the instance back to where it came from in the process before it was interrupted.
