Description

Description

Not able to create a list within a Table Section well as always having problems with ViewCells. If BindableLayout worked on a TableSection that would be most useful, or if the ViewCells could pick up these changes in the StackLayout.

Steps to Reproduce

  1. Create a Table View with a Table Section and ViewCell
  2. Then add a StackLayout with a BindableLayout.ItemSource and ItemTemplate
  3. Populate the Datasource this is bound to
  4. Items do not display

Expected Behavior

Items Display as expected

Actual Behavior

Items do not display because the ViewCell has no height

Contributor guide

Research direction
Investigate the layout cycle for TableView's TableSection when BindableLayout is used inside a ViewCell. Focus on how ViewCell measures its content and why items of BindableLayout.StackLayout may not get proper height.
