FEAT: Handling actions on notifications

[jasper07]

As per Developing Cloud Foundry Applications With Notifications this plugin covers:
Step 1: Publish the notification type
Step 2: Publish notifications

its missing
Step 3: Handling actions on notifications

It would be nice to get this in a plugin also, looks like you would need to persist the generated NotificationId to correlate back to the Entity the action was far

UPDATE: You can add your own NotificationId but it means you still need to persist this ID to correlate with the callback.
