I am creating an application using WAB. We have a Parcel Feature class with over 1 million parcels and many of them are multi part polygons. I need to be able to edit parcels, sometimes cutting or sometimes marge two of them. When I cut a multi part polygon in WAB it behaves as it does in ArcMap, cutting a multi part polygon (MPP), it creates two multi part polygon. In ArcMap I have the option to use explode option to manage this multi part polygons and then marge them if it is necessary. In WAB, I do not have any option for that an when I create a new parcel from a multi part polygon, there is no way how I can separate this parcel from the MPP and give it a new parcel number.
So, my question is, is there a workaround for this situation? is there a geoproccesing tool or a custom widget created by users with the same problem that I do know about?
Thanks for all your help!
