Question 360
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 plug-in assumes all Create requests include a company name and throws a null-reference exception when another client omits it. Which result BEST proves the intended fix is effective?
Explanation
Correct Answer
A missing required value produces a controlled business error rather than an unhandled null-reference failure. This directly tests whether the reported failure has been corrected: A plug-in assumes all Create requests include a company name and throws a null-reference exception when another client omits it. The intended action was Validate InputParameters and Target attribute presence before using optional values and return an actionable validation error. The observed Brookside Manufacturing outcome is stronger evidence than a completed ticket or a saved configuration alone.
Incorrect Answers
The listener receives one intended business event per approved transition and not unrelated field edits. Such evidence would validate a different change: A Dataverse business event publishes every minor update to a remote listener and floods the service with irrelevant events. It follows the separate remedy Configure supported business-event notifications or targeted steps for meaningful state transitions only. The Brookside Manufacturing scenario instead reports A plug-in assumes all Create requests include a company name and throws a null-reference exception when another client omits it. The decisive observation must be: A missing required value produces a controlled business error rather than an unhandled null-reference failure.
Both before and after values appear in the execution context and the status audit records the correct transition. Such evidence would validate a different change: A PostOperation plug-in must compare final persisted status with the pre-update status but cannot see the new value in its image. It follows the separate remedy Register the needed Post Image and appropriate Pre Image on the Update step. The Brookside Manufacturing scenario instead reports A plug-in assumes all Create requests include a company name and throws a null-reference exception when another client omits it. The decisive observation must be: A missing required value produces a controlled business error rather than an unhandled null-reference failure.
When the synchronous operation fails the expected transactional changes roll back consistently. Such evidence would validate a different change: A developer assumes a synchronous plug-in's related record operation is committed independently of the originating transaction. It follows the separate remedy Design related writes with the Dataverse transaction stage and explicit failure semantics. The Brookside Manufacturing scenario instead reports A plug-in assumes all Create requests include a company name and throws a null-reference exception when another client omits it. The decisive observation must be: A missing required value produces a controlled business error rather than an unhandled null-reference failure.
