resizing sfixed number

i want to resize a sfixed number of size(9 downto -6) to sfixed/signed of size (9 downto 0):

here's the code:

library IEEE;

use IEEE.STD_LOGIC_1164.ALL;

library ieee_proposed;

use ieee_proposed.fixed_pkg.all;

USE ieee.numeric_std.all;

ENTITY dwt IS

END dwt;

ARCHITECTURE dwt_behaviour OF dwt IS

signal k : sfixed(9 downto -6) ;

signal kk : signed(9 downto 0);

BEGIN

k <= "1100110011000010";

kk <= signed(resize(signed(k), kk'length)); -- error line

END dwt_behaviour;

error is:

Index value -6 (of type std.STANDARD.NATURAL) is out of range 0 to 2147483647.
