I am getting the exact same results as jonathan. But according to the documentation, this is totally legal. In this thread, the theory was that the IUID was not there or that the object needed to be dynamic, but that cant relate to an ArrayCollection. This really feels like a bug because I should be able to create and modify a bindable arrayCollection without worrying about any wierd scenario. This should be flex 101.
So I am curious if anyone else can dynamically (not from a data service) create a dataProvider for a dataGrid using an arrayCollection and select any item in the list with the mouse.
Betcha cant.

public class ResourceVO implements ValueObject{

}
}
The Issue:
When I view this application, it works as expected: it shows the datagrid with the three items and when I click on it, the fields to the right are populated. However, the blue selection highlight doesn't move off of the last item in the list! I have also sceen this issue in a ComboBox.
Any ideas as to why this is happening?
