MEDM REQUEST menu wrong if list of requestable states changes while running
As part of the IFO recovery today, I had trouble with the ALSX guardian getting stuck in Adams new guardian state (I cant recall what it is, but he will know), and when I tried to get out of that state by requesting other states via the pull down options on the ALSX guardian node, nothing would move.
Adam informed me there is a bug that this happens some times and to get around it, you go to the "all" state in the guardian node and from there select what state you wish to be in.
Submitting to see if we can get this bug fixed.
See LLO log 47656
More details on the bug: the state names on the pull down request menu on the automatically generated guardian medm screen sometimes get linked to the wrong state.
E.g. In the ALS guardian you might select PDH LOCKED from the pull down menu, but it might actually request the PZT MIRRORS OFF state instead. To know what state is actually being requested, look at the field above the pull down menu.
The ALL menu is a safer way to request states.
This is an old bug, and there's probably already a ticket floating around. The current fix is to restart the offending guardian code, but it can be difficult finding a convenient time to restart the code.
