We just upgraded from 7.5.13 to 7.7.5 and I am experiencing an issue now that I had not caught in testing.
When importing edited UDTs the alert mode (.AlertMode) property is getting lost. My existing legacy alerting tags are all working fine and will return a value for the .AlertMode property but once they are exported and then re-imported that property no longer exists.
If I try to write to that property for an UDT instance that has not been re-imported it works with no problem. If I do so on an instance of a imported UDT I get the error “The specified tag does not exist.” Trying to edit it with system.tag.edit also does nothing.
Is this a bug or are we not allowed to import UDTs with fully functional legacy alerting?
