problem using long raw in trigger

I need to write a trigger that copies a value out of one table into another and i'm experiencing great troubles in copying the LONG RAW field.

for example:

table: Y ( Y1 integer, Y2 varchar2(20), Y3 long raw) table: X ( X1 integer, X2 varchar2(20), X3 long raw)

trigger: Y to X before insert or update on Y referencing new as new and old as old for each row

           begin
                insert into X (X1,X2,X3) values (:new.Y1, :new.Y2, 
:new.Y3);
           end;

now i only get the first 2 values in the table without the long raw !!

Can any1 help me here !!!!!??????
