What the exam expects
- Explain why a Data Table column can't be searched and why a selectrow listener sees only one row.
- Fix a chart that renders at double height in a standard Flexcard component.
- Read the action debugger to find why a Data action's response never reaches the card or a child card.
- Keep navigate and close actions working inside modal and popover flyouts.
- Diagnose an autolaunched flow data source that returns old output or rejects an input type.
- Explain why a record change listener on an Experience Cloud page doesn't refresh after a backend update.
Key terms: Ignore Response (Data action option that skips updating the card's JSON), Response Node (where a Data action saves returned data), closemodal (the event name that closes a modal flyout), selectrow (the Data Table event for the currently selected row), record change listener (an event listener that reacts when a record on the card changes).
