Is defining a CursorSchema for a CursorAdapter class important if the data source is a native VFP8 table?

Also, when using the DataEnvironment builder and defining my CursorAdapter, I get an error that my CursorSchema can not be over 255 characters. Is this just a limit of the builder? If I have many fields in my table, should I create my CursorAdapter manually to avoid this size issue?

Thanks,
