***Note from Migration:***
Original Title was: Warning for deleting a workspace, if it is still scheduled task for this job available!
An important alarm message should be implemented that a warning appears on the web interface when deleting a workspace if there is an associated scheduled job.
Currently, only the workspace is removed (without reference to a scheduled job).
If the workspace is deleted, the scheduled job is still active, and then logically fails.
Ideally, a query would be desirable if the associated scheduled job should also be removed.
