Explore the behavior
Branch before fetching
status; the next result must contain exactly that ID. Put an expensive data query inside the matching branch.
Merge rules
target: '*'requests the full matrix.- A partial response must contain exactly the requested IDs, with no extra or missing cells.
- Retained INPUT values and drafts are not reset by an ordinary refresh.
- An invalid partial response is rejected; it is not treated as an empty dataset.
- A default overlapping read uses latest-result behavior, protecting against stale responses.
Ordered commands
Useconcurrency: 'queue' on a REFRESH action when each command depends on the result of the previous one, such as calculator keys. This is a per-frame UI command queue, distinct from Job concurrency.
This action fragment assumes a display cell exists:
$widget.event.sourceId to identify the command. A synchronized INPUT can hold the resulting value.
At most 64 commands may wait. Overflow clears pending commands and shows an error. Errors, manual refresh, nonqueued refresh, remount and Back cancellation also discard pending commands. This option does not queue writes or persist state across a page reload.
Timers
Cellrefresh.intervalSeconds accepts 1–86400 seconds. Optional targets names the cells to refresh instead of the timer cell. Hidden frames pause reads, and overlapping interval reads are skipped. See header controls and timers for whole-widget refresh and its fallback behavior.
