How to delete a snapshot view from CCRC when "Remove ClearCase view" is disabled?

I'm running a system with Clearcase Remote Client version 7.0.1.CU04.
I don't have cleartool installed on the system, so a command-line solution for my problem is probably unavailable to me.

Inside of CCRC, I've created many views that appear in the ClearCase Navigator pane.
I'd like to delete these to reduce clutter, but see no UI options to do it.
Right-clicking will show me a disabled "delete" in the pop-up menu list. And also the "Remove ClearCase View" under the "Environment" menu is disabled. Deleting the associated directory in the filesystem (not CCRC) will just leave an orphaned item in the list shown in CCRC.

How can I delete these views?

Solution

I confirm that ~~CCRC doesn't come with any cleartool CLI~~ -- scratch that: with CCRC7.1 onwards, you do have a CCRC Remote CLI (including a rmview command!).
They can be deleted on the CCRC server where they are listed as ccweb views, like this technote mentions.
But it also mentions:
"The proper way to remove a ClearCase Web view is through the CCWeb interface or CCRC interface."

So it must be possible (and has always been, according to the feature matrix).

Select a view
Right-click and select Remove ClearCase View (not "delete")

Are your views within a working set?
