I am using the Edit Widget and the Batch Attribute Editor widget to edit our Feature Layer. I would like to be able to modify two attributes when the Edit is Complete with these widgets. I would like to update a date field and a user field. I know this can be done via the Editor Tracking Fields, but the layer is edited in ArcMap and I only want to update the attributes when an edit occurs via WAB. Is there a place in WAB where I can put some custom code to set these attributes when an edit is compete?
