GENERIC MAP issue

I inherited some code that includes the following:

---

r_comp: component c_rcomp

generic map (init => "11111111")

port map (

in1 => in_a,

nclk => nclk,

q => re(0 to 7)

);

--

Quartus 9.1 generates an error:

Error (10349): VHDL Association List error at re_ots.vhdl(145): formal "init" does not exist

=======

How do I fix this?

Thanks
