I have seen this topic a few times on locked posts from months ago but I haven't seen a solution. It seems that eventInfo.previousValue returns what the field has been set to(eventInfo.newValue) when the user enters data into the field for the first time. Even putting a default value in the field does not stop this behavior. Thanks

This has been tripping me up over the weekend too.

The only good thing is that as far as I can tell eventInfo.newValue == eventInfo.previousValue can only be true in this one case, since not changing the feild wont trigger the event. so you can say if(prev == new){prev = undefined} and that worked for me
