  - ### addHandleErrorHandler

    HandlerRegistration addHandleErrorHandler(HandleErrorHandler handler)
    If you define this method on a DataSource, it will be called whenever the server returns a DSResponse with a status other than `STATUS_SUCCESS`. You can use this hook to do DataSource-specific error handling. Unless you call `ErrorEvent.cancel()`, `HandleErrorCallback.handleError()` will be called by Smart GWT right after this method completes.
    Parameters:
      `handler` - the handleError handler
    Returns:
      `HandlerRegistration` used to remove this handler
