Geoprocessing Service - Dynamic Layer Parameter and Dynamic Field Choice Parameter

Question asked by kirby.lance3665 on Jun 22, 2020

I'm trying to create a geoprocessing service with two parameters. The first is a dropdown for the user to select any feature layer in the WAB application. The second parameter should be a list of fields which exist in that feature layer. Is this possible? From what I understand I can not use tool validation to achieve this behavior so I was hoping to simply set the second parameter dependent on the first in order to accomplish this workflow.

 

Does anyone know if this is even possible?
