Ah, I see now. We’ll work on getting those fixed for the actual demo project. In the meantime, the acknowledge button can be made to work relatively easily. The script it runs depends on custom properties that are supposed to point to the column with the Tag Path, but it doesn’t. The properties just need their bindings changed so they point to the correct columns.
The acknowledge all button is a little trickier. The script it calls used to acknowledge all alerts if you passed in blank strings, but that doesn’t work any more either. So you’ll have to loop through all the active alerts using system.alert.queryAlertStatus().
We only recently had this brought to our attention, so a fix from our end should be coming soon.
