The example in the TreeList binding to remote data uses "jsonp". I tried "json" and it didn't work.
I have 2 questions:
1) does TreeList binding to remote data only support "jsonp"
2) in the example, when clicking on the tree list node, it includes "id=1" in the query string. Is the name "id" hardcoded? Is it configurable to have "studentId=1" in the query string?
