A REST query will return a JSON response. It is very easy to get a value for a field. However, if the query is done on a featureclass that has been JOINED.... the field names are no longer simple, but instead have the table name included .... such as streams.width.
features[0].attributes.streams.width gives an error. It does not like the two part name. If I assign an alias to the field, how can I use it?
Thanks
