--------------------------------------
Summary: TaskManager page keeps showing "no longer registered"
after switching to another TaskManager
Key: FLINK-41418
URL: https://issues.apache.org/jira/browse/FLINK-41418
Project: Flink
Issue Type: Bug
Components: Runtime / Web Frontend
Affects Versions: 2.4.0
Reporter: Martijn Visser
Since FLINK-31931 the TaskManager page stops polling once the TaskManager
returns 404. Angular reuses TaskManagerStatusComponent when only the
taskManagerId route parameter changes, so the not-found flag stays set and the
poll has already completed. Changing the URL from a stopped TaskManager to a
registered one keeps showing "This TaskManager is no longer registered" and
sends no request until a page reload. Reproduced on master at 2e89b879f1e. The
poll should restart per taskManagerId, for example by switching on
activatedRoute.params.
