The exact thing that Jonathan describes below in the referenced email is happening to me. I am attempting to programatically create a bindable arrayCollection and use that arrayCollection as a dataProvider for a dataGrid. When I do this, only the last item in the list is selectable with the mous

I agree but the pattern of use for casting using Class( obj ) collides directly
with global functions created for type conversion. If the following methods are
used to upcast an object, these can wildly change the va
