Thanks for the suggestion, that worked. Now what I find odd is that when using the listKey/listValue parameters for the autocompleter tag, it doesn't populate the dropdown when the data is sourced from a remote URL. If I request the Ajax service, I get the serialized data as I would have expected, but for some reason the widget isn't populating the dropdown with it now.
