In Pega Constellation, you can achieve real-time update notifications in the case UI without creating a custom DX component. Here’s how you can resolve the JSON failure message while editing pyStages view and implement the refresh notification banner effectively.

Possible Causes of JSON Failure While Editing pyStages View

1. Schema Mismatch:

   • Ensure that the banner widget configuration follows the expected JSON schema for Constellation views.
   • Any incorrect property reference or missing metadata could cause the failure.

2. Unsupported Customization in pyStages

   • The pyStages view is an OOTB system-generated view in Constellation. Some UI modifications may not be allowed directly.

3. Job Scheduler Updates Conflict with UI

   • If the Job Scheduler is updating properties on a case, it could create a conflict when trying to edit a system-generated view (pyStages).

Solution Approach: Using case.processingStatus to Display Refresh Notification

Since Constellation does not allow direct UI customization like in Traditional UI, use case-level metadata to trigger refresh messages dynamically.

Step 1: Utilize case.processingStatus to Track Updates

• case.processingStatus is automatically updated when a case is modified in the backend.
• It is referenced by the Constellation framework to determine when a refresh is required.

Step 2: Configure a Refresh Message Using a Banner Widget

Instead of modifying pyStages, configure a banner widget inside a custom case view.

1. Navigate to your case type → Views

2. Create/Edit a case-wide view (e.g., pyCaseMainView or pyCaseHeader).

3. Add a Banner Widget with a condition based on case.processingStatus.

4. Configure Visibility Conditions:

   • Show the banner only if the case is updated in the backend.

Step 3: Automatically Refresh the UI When Case Data Changes

1. Ensure case.processingStatus is updated in the Job Scheduler

   • Modify your Job Scheduler to set a property (e.g., UpdatePending) when it updates the case.

2. Enable Auto-Refresh in Constellation

   • Constellation UI detects backend changes automatically and prompts the user.
   • If needed, set up a Polling Data Page to periodically check for updates.

Alternative: Using the pyWorkPage Metadata Approach

If case.processingStatus does not trigger updates reliably, use a custom case property.

1. Update a property (e.g., .RefreshRequired) in the Job Schedule

2. Use a condition in the UI to display the banner

   • Add a visibility condition:

Final Thoughts

• DO NOT edit pyStages directly in Constellation.
• Use case metadata (case.processingStatus) to trigger UI refresh.
• Add a Banner Widget in a case-wide view (e.g., pyCaseMainView).
• Ensure the Job Scheduler updates the metadata to inform UI about backend changes.

This approach ensures that users get a real-time refresh notification without breaking Constellation's architecture.
