widget-coherence

Service Portal widgets break when server data, client actions, and HTML bindings drift apart. Enforcing a three-way contract ensures the server initializes data, the client implements actions, and HTML only references server-provided data to keep them in sync.

To validate data binding consistency, ensure the server initializes all data, the client exposes methods for every server action, and the HTML template references only server-provided data. Then test ng-click interactions and data flow end-to-end.

The three-way contract requires the server script to initialize data, the client controller to implement actions for server calls, and the HTML template to reference only server-provided data. This coordination prevents widget communication failures.

Yes, the widget coherence check applies to widget creation, modification, and debugging scenarios. It validates that ng-click actions trigger proper server responses and that HTML reflects updated data across the widget lifecycle.

The best approach is enforcing the three-way contract where the client controller implements every action method that ng-click references, ensuring server responses update data that the HTML template properly binds and displays.
