This is on 8.3.4-RC1.

I have a pop-up that only has an AlarmStatusTable control and a custom string property called AlarmPath, everything is the defaults except there is an expression binding on the Source Filter property:

`”*” + replace({Root Container.AlarmPath}, "[default]", "") + "/*"`

This works just fine, until I do the following:

- Open the display for a tag path (no errors shown)
- Shelve the alarm
- Close the display
- Open the display for a different tag path

Once I do that, the following error is displayed:

```python

Java: Azul Systems, Inc. 17.0.17

```

This looks like an internal error, something with the “ShelfManagementPanel” callback… Once the alarm is unshelved (either by timeout or explicitly doing so) the exception goes away.

Thanks, this is indeed an internal error. We fixed some other issues with the AST/AJT in Vision in 8.3.4, but this one slipped through the cracks. We'll get it fixed, but no promises on a timeline.

This will be fixed in tomorrow's nightly and in the 8.3.6 release.
