Ken Evans was the last real maintainer of MEDM and I think he retired
before we added the DBE_PROPERTY event type to Base, so I don't think
you're going to get any responses to that question.

I have an alternative suggestion which may or may not work for your
issue depending on how dynamic your enum strings are: Replace the Menu
Button pointing to your enum with a Text Update widget (to display the
current setting) and a series of Message Buttons, one for each
possible value, each of which will put their specific command string
to the enum record on pressing the button.

By putting a string value you don't care if the numbers for the enum
commands change. You will also want to arrange for the buttons for
those commands not currently enabled to be disabled (made invisible),
which will probably need additional PVs to work. This does couple your
MEDM screens more closely with your application, but that might not be
too much of a problem.

HTH,
