• Resolves: workflowengine: File entity reuses the node of the first "Tag assigned" event for all later events in the same process #66618

Summary

The File workflow entity is shared within a process, and getNode() keeps the node it looked up for a "Tag assigned" event. prepareRuleMatcher() never cleared it, so in cron every later event in the same run was checked against the first file. The cached node is now reset when a new event is prepared. Added a unit test with two tag assign events that fails without the change.
