The default for HTTPService is resultFormat="object". This causes your xml to be converted into a nested structure of dynamic objects. The Flash Player has always had a problem differenticating between an Object, and an array with a single element.
I advise changing to resultFormat="e4x" and working with your result as XML, which does not have this issue, and has a lot of other advantages as well.

On the other hand if you add one more item in the input xml file, then it returns an arraycollection with 2 elements. I guess this is a bug!!!!
