Selection on native Oracle table can fail to highlight features

[brucedechant]

If you try and select a feature from a native Oracle table the feature will not select (highlight) under certain conditions. The issue is that when the server is doing selection (highlighting) it cannot handle feature IDs that have a data type of single or double. When the server encounters a data type of type single or double for the feature ID it will throw a MgNotImplementedException exception.
