Problem with Component Editor in SOPC Boilder

Hello everyone.

I have a little problem with Component Editor in SOPC Builder.

I tryed create SOPC Builder component using my own IP core which has got entity such as:

entity key_pad_with_clk_div is

generic(

SIZE : natural := 1

);

port(

chipselect : in STD_LOGIC;

clk : in STD_LOGIC;

read_n : in STD_LOGIC;

reset_n : in STD_LOGIC;

write_n : in STD_LOGIC;

address : in STD_LOGIC_VECTOR(1 downto 0);

sw_in : in STD_LOGIC_VECTOR(SIZE-1 downto 0);

writedata : in STD_LOGIC_VECTOR(15 downto 0);

irq : out STD_LOGIC;

waitrequest_n : out STD_LOGIC;

readdata : out STD_LOGIC_VECTOR(15 downto 0)

);

end key_pad_with_clk_div;

but SOPC Builder Component Editor do not let my use variable length of input port "sw_in : in STD_LOGIC_VECTOR(SIZE-1 downto 0)". When i see Preview the Wizard which is part of Component Wizard I can see this:

----------------------------------

Parameters

SIZE:

----------------------------------

Parameterized signal width

sw_in[(size-1) - (0) + 1]: -1

----------------------------------

and it doesn&#39;t matter which "SIZE" I insert. Inserted parameters do not change size of sw_in. The sw_in is always one bit range. Please help me.
