How do I get the _pageid using wwpro_api_parameters for a form published as a portlet

Question

Hi, I need to be able to determine which page my form component is running on.
Is it possible using the pl/sql api to determine the value of the _pageid parameter?
The wwpro_api_parameters package does not expose all of the parameters in the URL. I need the _pageid parameter.
The only alternative I can think of, is to output some Javascript in the before form PL/SQL section that stores the document url in a cookie, which is then retrieved using the OWA_COOKIE package.
Surely there is a better alternative?
I am running 3.0.9.8.1 (patched) on Windows NT.
I know report components published as portlets have access to p_page_url? Is there something similar for form components?
I know I am unlikely to get a response!
kind regards,
Matt.

Resorted to cookies!
Before page pl/sql ...
begin
htp.p('^script language="Javascript1.1"^SetCookie("PageURL",unescape(document.location),expire(1,0,0,0),"/",".disney.com");<^script^');
end;
declare
lv_page_url VARCHAR2(256) := null;
pageurlCookie owa_cookie.cookie;
ln_type_id number := -1;
lv_currenttab varchar2(64);
begin
begin
pageurlCookie := owa_cookie.get('PageURL');
if pageurlCookie.num_vals != 0 then
lv_page_url := substr(pageurlCookie.vals(pageurlCookie.vals.first),1,256);
end if;
exception
when others then
null;
end;
if lv_page_url is not null then
lv_page_url := bvhe_page_utils.unencode(lv_page_url);
end if;
lv_currenttab :=
bvhe_portal.bvhe_page_utils.get_idname(
bvhe_portal.bvhe_page_utils.process_pageid(
bvhe_portal.bvhe_page_utils.get_pageid(lv_page_url)
null
