We have a use case for a user in ExB to draw a polygon and then pass that as an input spatial filter to an external url (fme server).
I was thinking the Draw widget was nice since it doesn't persist like a Markup HFL would. But can any other widgets interact with the graphic? And can the geometry be retrieved in a List widget, or the like?
Similarly, can I get the json for the geometry of an object in ExB?
