Question 340
A control renders only its first page and users assume that every customer order has been displayed. Which evidence should the developer inspect FIRST to distinguish the root cause or verify the prerequisite?
Explanation
Correct Answer
Inspect dataset loading flags, records page, sorting state, paging.hasNextPage and selected record IDs. These observations separate this failure from adjacent capabilities or permissions. Data-set PCF hosts may supply paged data; a single loaded page is not a complete table. The relevant implementation is: Build dataset PCF components that use provided paging, sorting and selection APIs rather than assuming all rows are loaded.
Incorrect Answers
Inspect control manifest property of-type, usage, component namespace, platform libraries and compiled resource paths. These checks are relevant to PCF ControlManifest inputs and resources, but are not the most discriminating first evidence for this case. Inspect instead: Inspect dataset loading flags, records page, sorting state, paging.hasNextPage and selected record IDs.
Compare available business-rule scopes, related-row access, API restrictions, field change triggers and testability. These checks are relevant to Form business rule versus custom client JavaScript, but are not the most discriminating first evidence for this case. Inspect instead: Inspect dataset loading flags, records page, sorting state, paging.hasNextPage and selected record IDs.
Inspect browser network errors, telemetry configuration, sampling, request correlation, exception events and user consent. These checks are relevant to Code app Application Insights instrumentation, but are not the most discriminating first evidence for this case. Inspect instead: Inspect dataset loading flags, records page, sorting state, paging.hasNextPage and selected record IDs.
