[flexcoders] Re: List dragMoveEnabled problem?

[jasondrubenstein]

and, if I write code to convert the XML to an ArrayCollection, and
bind to the new ArrayCollections, everything works fine. 

So it seems the problem is when I'm binding to XMLListCollection. 
Binding to an ArrayCollection is behaving as expected. 

This is a workaround, but there shouldn't be a problem when using
XMLListCollections, I'm guessing?
