HTML DB authorisation via PL/SQL bug?

Question

I tried to implement a simple authorisation package and failed. This seems to be a bug in HTML DB.
See below for package body. I have a function check_user and a procedure check_user2.
When I enter a call to the procedure in my Authorization Scheme (PL/SQL Function Returning Boolean) I get what I deserve:
auth2.check_user2(:APP_USER)
results in: ORA-06503: PL/SQL: Function returned without value
When I use the function instead however the error I get seems less justified:
auth2.check_user(:APP_USER)
ORA-06550: line 1, column 44: PLS-00221: 'CHECK_USER' is not a procedure or is undefined ORA-06550: line 1, column 44: PL/SQL: Statement ignored
It seems HTML DB is checking to make sure it finds a 'procedure' - but it really needs a 'function'...
Just for completeness the package body:
create or replace package body auth2
is
function check_user( P_USER IN VARCHAR2) return boolean
as
begin
insert into hr_log (log_txt) values (p_user);
return True;
end check_user;
procedure check_user2( P_USER IN VARCHAR2)
as
begin
insert into hr_log (log_txt) values (p_user);
commit;
end check_user2;
end auth2;

Peter - When HTML DB calls for a Function Returning Boolean it's looking for you to have specified a call to a function whether you put the code within a begin-end or you let HTML DB do it. What you entered was (when framed in begin-end) syntactically a procedure call within an anonymous block. Try entering "return auth2.check_user(:APP_USER);" (without quotes).
