I've been able to successfully create a survey with nested repeats and everything works fine. The problem comes when I'm trying to view and proof my collected data. What I want to be able to do in WAB or Ops Dashboard is select a parent record and be able to see the related grandchildren, not just the children. I know I could probably accomplish this in WAB by creating a custom widget, but I'm trying to avoid going down that route.
My initial attempts involved trying to create a relationship class b/w parent and grandchildren to be able to take advantage of the 'Show related records' in WAB or actions w/ filters in Ops Dashboard. This didn't work when I tried the two following approaches:
Here's my workaround:
I create a common key (concatenated text which uniquely identifies all features as being in the same survey) in each of my features (parent, child, grandchild) and I use this field in the group filter in WAB or using actions/filter in Ops Dashboard.
Has anyone come up with a better solution for this functionality?
