Creating a master detail with this relationship:
Parent (1) ---> Child(0 or 1)
The details page shows the child record greyed out.
I realise this is because Lightswitch doesn't know if it should create a record.
When trying to add an existing method, "Add/Edit Child" is not available.
Question is, what javascript code do I put in a button to create the child record?
Or is there another way to do this with maintaining this relationship structure?
