Hi Tong,

If you don't see org.phoebus.pv.ca/monitor_mask in the preferences, it's using the default, which is VALUE.

I agree that it's unfortunate that you can't see all available settings in the Help, About, .. preference listing.

Way back when we started phoebus I had suggested a way of using the java preferences in a way to give us all settings, no matter if they're at the default or changed, https://github.com/ControlSystemStudio/phoebus/issues/4, but we ended up doing it such that the running instance can only list changes, for a complete listing you have to go to the online help.

> Can you offer any approach for further investigation?

Try to come up with a reproducible example.

I've described one based on the demo.db and opi that are included in the alarm examples, and that looks fine when I run that here.

See if it works for you.

Well, I can't reproduce this.

Under https://github.com/ControlSystemStudio/phoebus/tree/master/app/alarm/examples, there's a demo.db and associated display.

I'm running a softIoc with that demo.db, add the test_alarm PV with enabling filter "test_enable>0" to the alarm tree, and then use the demo.bob display for the following:


1) Set test_alarm = 10, it shows up as MAJOR alarm in alarm table and tree
2) Set test_enable to 0. test_alarm is shown in gray with "(disabled)" in alarm tree, and not at all in alarm table
3) Set test_enable back to 1, and test_alarm shows back up as it looked in step 1
