Order of iteration under plan in team artifacts view is reverse of what it is in time line tree.
Create a Scrum Project area using the RTC Eclipse client.
There will be Sprint 1 and Sprint 2 Iterations already defined.
Add Sprint 3 and Sprint 4 Iterations as will in the Time line tree.
In team artifacts view expand the [New Project area ] --> Plans --> All Plans --> Main Development --> Release 1.0.
