I have two data sources, Commissions and Tasks (1:Many) which are linked by the Commission ID.
On the app I have a gallery (CommissionGallery) showing a list all of the commissions, and then a form (CommissionForm) next to it which users can view/edit the commission.
Commission is split into 4 sections, one of those sections is "Tasks" and within that section I've got another gallery (TaskGallery) showing a list of the tasks for the selected Commission in CommissionGallery (shown in the first image)
That part is all working perfectly, having the tasks in CommissionForm means I can have the sections be collapsible instead of showing the tasks on a different screen/visible property set to show on a button etc.
Problem: I want to be able to view/edit the full task details in a pop-up window which includes another form (TaskForm) (see the second image). I have the item property set as TaskGallery.Selected, which works when TaskGallery is not contained within a form, but when its within CommissionForm the popup (TaskForm) shows "No item to display" when its in live mode or just blank in studio, except for the Commission ID.
I assume there's too many form from a gallery within another form coming from another gallery problems.
Apologies for the annoying blocks, hopefully it still makes sense
