When a supporter is added to the list, it does not auto-select the supporter after saving it to the list. The ID seems to be the culprit as when trying to save with the newly created supporter causes a non-numeric error.
Records were properly being created. The JSON return variable name was different than expected (Coldfusion seems to capitalize all JSON variable return names while Railo seems to leave them spelled as is).
