RestService, output mapping, WidgetTree not updated after adding the service
Steps to reproduce:
1) Create new mobile web app
2) Add a grid (for input parameters)
3) add a RESTService (using echo server)
4) add more components to the grid
5) add a another grid (for output)
6) choose the service from 3) and select output mapping
Now you cannot see the grid and components under 5). I believe that the rest service just sees things up to itself has been added.
Workaround: Save Project, Close, Re-open in editor.
(I did not reproduce this, but tried to describe what I saw as a steps to reproduce, it seemed like a natural guess at where the problem could lie.)
