Solution works well in practice too!!!
I was using the files from the zip but will now use the (updated) framework. Now that the update and refresh are working I am moving on to figuring out how to prevent the user from editing the updated value once set.
Thanks again.

Or would having AjaxNotificationCenter extend ERDCustomEditComponent be the better way to go and include in displayPropertyKeys? I am looking to have a selection from a popup (ERD2WEditToOneRelationship) set some text field values. Using the delegate pattern from your example I know my attributes are getting set but so far haven't been able to get the AjaxNotificationCenter on the page.
