In Flex 4/Spark, the dataProvider contract is limited to IList implementations (the Flex framework provides several IList implementations straight out of the box like ArrayCollection, ArrayList, XMLListCollection, XMLList, etc). We decided to do this to reduce complexity which in our dataProvider-aware controls. As part of this, we now don't auto-wrap raw data like Array or XML into ArrayCollections or XMLListCollections, which is why you need to do that manually.
