All that you're using in the ArrayCollection are the length property and [] to access its items. Both are also available for the Array, so no special handling here. Could you post the whole error messages or better an example that we can compile and having the same problem?
Anyway, you have to use ciData and not dp! It makes no sense to use a HTTPService object like that.
