TXDataClient RawInvoke need RequestId AND SuccessProc

Actually exactly the "InternalRawInvoke" procedure. :slight_smile:

procedure TXDataWebClient.InternalRawInvoke(const OperationId: string;
  Args: array of JSValue; const Query: string; RequestId: string;
  SuccessProc: TXDataClientLoadProc; ErrorProc: TXDataClientErrorProc; AsyncMode: Boolean = False);
