I'm really new to Flex and I was following a tutorial. When the tutorial inserts a data grid component, it gets inserted as a spark component. When I insert a data grid component, it gets inserted as an mx component. I think I'm using the same tools as the tutorial. Why do I see a different component (out of the box on fb 4 premium)?
Nevermind...I stumbled onto the answer. I was using fb 4 and the tutorial was using fb 4.5. When you select a datagrid component in fb 4 you get an mx component. When you select a datagrid in fb 4.5 you get a spark component. When I checked for updates inside of fb 4, it said no updates were available. I had to download and install fb 4.5 separately.
