ClassCastException in RTCModel.java

Question

Hi,
I found a problem in the RTCModel class. When I call fetchItems(room, "default_SimpleChat", "history") to obtain the chat history, the RTCModel fails with an exception:
ClassCastException: Cannot cast java.lang.Double (id=3330) to java.lang.String
The problem is located in the addItem function within the Node inner class:
    public void addItem(Map<String, Object> data)
        String itemID = (String) data.get("itemID");
        if (itemID == null)
            itemID = "item";
        items.put(itemID, new Item(data));
The String cast isn't checked and the itemId contains a Double 0.0.
The data returned by the service is:
[default_SimpleChat={
     nodes={
          history={
               items={
                    0.0={publisherID=EXT-MYACCOUNT-3499,
                         body={color=0.0, role=10.0, displayName=Test User, msg=test1},
                         itemID=0.0,
                         timeStamp=1.282144187104E12,
                         associatedUserID=EXT-MYACCOUNT-3499,
                         nodeName=history,
                         collectionName=default_SimpleChat},
                    1.0={publisherID=EXT-MYACCOUNT-3499,
                         body={color=0.0, role=10.0, displayName=Test User, msg=test2},
                         itemID=1.0,
                         timeStamp=1.282144188111E12,
                         associatedUserID=EXT-MYACCOUNT-3499,
                         nodeName=history,
                         collectionName=default_SimpleChat}
To fix the problem, I changed the get to:
String itemID = String.valueOf(data.get("itemID"));
Does that make sense?
Thanks!
