Hi, I'm working with Arash on this project. Thanks for the suggestions but even using these alternate methods for geting the selectedItem the cast to a Position object still fails.
Our dataProvider is an ArrayCollection that is populated by a ColdFusion query returned from a RemoteObject call. The query rows are from our positions table but flex is storing the rows as generic 'Objects' within the ArrayCollection. Here is the line we use in our RemoteObject result handler: positions = event.result as ArrayCollection; Using the debugger we've been able to verify that the Objects in the ArrayCollection do have the same public properties as our Position value object. So is it necessary to convert the query rows into Position objects immediately when they come back from ColdFusion rather than casting them after we get them out of the ArrayCollection? How would this be done exactly? Adam --- In [email protected], "ben.clinkinbeard" <[EMAIL PROTECTED]> wrote: > > I assume your dataProvider is a collection of Position objects?
