HOW to pass page parameter into table function in HTMLDB

Question

I created this object and table function in database.
create or replace TYPE date_flow_type
AS OBJECT (
time           date,
max_time      number,
avg_total           NUMBER,
sum_total      NUMBER,
max_total      NUMBER,
change_rate      number
create or replace TYPE date_flow_table_type AS TABLE OF date_flow_type;
create or replace function ret_date(p_date date default sysdate) return date_flow_table_type is
v_tbl1 date_flow_table_type :=date_flow_table_type();
begin
v_tbl1.extend;
v_tbl1(v_tbl1.last):=date_flow_type (p_date,1,1,1,1,1);
return v_tbl1;
end;
and it is correct in htmldb when using in these ways
SELECT TIME da,
     max_time max_time,
     sum_total total,
     max_total max_total,
change_rate
FROM TABLE ( ret_icp_date_flow ) a;
SELECT TIME da,
     max_time max_time,
     sum_total total,
     max_total max_total,
change_rate
FROM TABLE ( ret_icp_date_flow( sysdate-1 )) a;
but return error
ORA-00904: "RET_ICP_DATE_FLOW": 无效的标识符
when pasing page parameter into the table function
SELECT TIME da,
max_time max_time,
sum_total total,
max_total max_total,
change_rate
FROM TABLE ( ret_icp_date_flow( to_date(:p1_date,'yyyy-mm-dd') )) a
and this sql is correct while running in sqlplus .

Hi!
Thanks for your reply!
I have tried this solution but it doesn't work!
When I do getInitParameter in the init function, the servlet take the default values...
Maybe I have wrote something wrong?
Excuse me for my english,
Thanks
