Content that has been transcluded using {{:myPage}} (or as template {{myTemplate|param=foo}}) into a page (including its value annotations) requires that MediaWiki's "refreshLinks.php" maintenance script has been run first before changed values are made available to the Semantic MediaWiki backend (and hereby possible dependent queries and its result display).
This is even more important for use cases where {{:myPage}} itself transcludes data from a template and requires updates. The job queue is expected to be scheduled appropriately to ensure updates are dispatched within a short period of time to avoid a large backlog.
