Alarm pipeline notification block edit error

I am having trouble with the notification block - I cannot edit it in my pipelines anymore.

I had to update just the voice and alarm pipelines to fix another issue but i’m not sure if that is the root of my problem - the problem started after the update.

when I click on the notification block in the designer, I receive this error:

ExecutionException: java.lang.NoClassDefFoundError: com/inductiveautomation/ignition/client/util/gui/DebouncedCatchAllListener
	caused by NoClassDefFoundError: com/inductiveautomation/ignition/client/util/gui/DebouncedCatchAllListener

PS. It is just the notification block that is causing the error.

thanks for reading

That’s definitely the source of the problem. The class that’s missing was added in 7.9.4. I’m not sure why you upgraded just those two modules, but you’ll have to upgrade the platform/all modules to get the pipelines to work properly.

Thanks, will do - I figured as much. The upgrade was a quick fix i didn’t have time to upgrade the rest.
