Between version 4.16 and version 4.22 of the API, on the FeatureLayer's "edits" event, the "target" property (hence target.url) is no longer exposed/returned, which we use to perform a check, i.e., figuring out on which layer to go and update the an other field with the WebService 'Update_Features'.
Any images of code...

and

there's an other way to create a feature with an hidden field forced to a specific value?
thanks
