Question 200
At Brookside Manufacturing, the plant software team is implementing a work-order system upgrade under requirements for planned downtime and production traceability. The team says the following incident was fixed: A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. Which result BEST proves the intended fix is effective?
Explanation
Correct Answer
Multiple unchanged updateView invocations do not trigger repeated identical service requests. This directly tests whether the reported failure has been corrected: A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The intended action was Compare relevant changed properties and cache scoped results to avoid unnecessary calls on rerender. The observed Brookside Manufacturing outcome is stronger evidence than a completed ticket or a saved configuration alone.
Incorrect Answers
The component binds correctly to the intended column and validation rejects incompatible configuration. Such evidence would validate a different change: A PCF text control expects a numeric input but its component manifest declares the bound property as text. It follows the separate remedy Align the manifest property type, usage and bound column with the control's supported contract. The Brookside Manufacturing scenario instead reports A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The decisive observation must be: Multiple unchanged updateView invocations do not trigger repeated identical service requests.
The control handles two different view layouts without exceptions and shows only available columns. Such evidence would validate a different change: A PCF grid assumes every dataset column is returned and crashes when a view omits an optional field. It follows the separate remedy Check dataset metadata and column availability before accessing values, with a defined empty-state fallback. The Brookside Manufacturing scenario instead reports A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The decisive observation must be: Multiple unchanged updateView invocations do not trigger repeated identical service requests.
After repeated navigation no duplicate event handlers fire and memory use remains stable. Such evidence would validate a different change: A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. It follows the separate remedy Remove subscriptions, listeners and allocated resources in the destroy lifecycle method. The Brookside Manufacturing scenario instead reports A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The decisive observation must be: Multiple unchanged updateView invocations do not trigger repeated identical service requests.
