    - #### addHandleErrorHandler

          com.google.gwt.event.shared.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()`, `RPCManager.handleError()` will be called by Smart GWT right after this method completes.
      Parameters:
        `handler` - the handleError handler
      Returns:
        `HandlerRegistration` used to remove this handler
