I'm using the AA Validate Attribute Lookup method to populate the road directional, road name, road type and municipality fields in our Road Centerline feature class. Works well when the road directional field has a value (N, S, E, or W) but does not work if the directional field is null, which is the vast majority of cases. Popup opens with the message "The property values cannot be changed". It's validating against the MasterStreetName table.
Does anybody have a workaround or perhaps another method that would work?
