JSOHelper.convertMapToJavascriptObject() with Integer key?

[khkwang]

Is there any reason why this function expects a String as a key? Why can't I use a Map with an Integer as the key?

To specify, I'm trying to send an Integer keyed Map as a param through the RPCManager.

Thanks.

JavaScript Objects do not support property names of any type other than Strings.
