Issue with Request Closing Rules and Worklog ticked

We set the WorkLog mandatory in Request Closing Rules for incidents, so that our technician HAVE to document the work that they have performed.

Often, a request will include 1 or more tasks, and technicians will create worklogs associated with those tasks.

The system does not recognize worklogs that are assigned to tasks within a request and will deny the close attempt by a technician, telling him that no worklog exists.

As a workaround, in those situations, the technician has to create a dummy worklog entry straight from the request, not thru a task, in order to close the request.

Can this be fixed please, so that the system will recognize worklogs that are assigned to tasks within a request and let the technician close the request.

thx in advance.

We hoped that version 9.0 would address this issue, but tested this morning, and issue still present.
