How to open a page from a Form and pass parameters to the form on that page

Question

I found a similar example on this forum, but it did not work for me:
declare
l_names owa.vc_arr;
l_values owa.vc_arr;
i number;
begin
PORTAL.wwpro_api_parameters.retrieve(l_names, l_values);
FOR i in 1..l_names.count
LOOP
htp.p(l_names(i) || ' ' || l_values(i));
END LOOP;
end;
By using this method i get the parameters for the Form, like the session ID, but not the parameters for the Page that the form is displayed in.
Another method I tried:
To open a Form from a Form and pass parameters works fine like this:
--In the After processing page PL/SQL event.
declare
v_id number;
blk varchar2(10):='DEFAULT';
Begin
v_id:=p_session.get_value_as_number (p_block_name=>blk,p_attribute_name=>'A_ID');
if v_id > 0 then
htp.formOpen('PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=2649500412&p_arg_names=_show_header&p_arg_values=YES&p_arg_names=ID&p_arg_values='||to_char(v_id),'post');
htp.formSubmit(NULL,'Upload Files');
htp.formClose;
end if;
End;
But I want to open a Page containing the Form instead of just opening the Form. Is this possible to open a Page and pass paramters to the page, and then let the form inside the Page access the passed paramters. The reason for this is that a Form cannot be based on a page template, or can it? When opening the form i want to keep the left menu, which I can if it is a page based on my template with the left menu.

Hi,
You can do this by calling the url of the page with the form. You can then use p_arg_names and p_arg_values to pass parameters. In the called form you can get the value from p_arg_names and p_arg_values and assign it to the form field.
You can call this code in the success procedure of the calling form.
declare
v_id number;
blk varchar2(10):='DEFAULT';
v_url varchar2(2000);
Begin
v_id:=p_session.get_value_as_number (p_block_name=>blk,p_attribute_name=>'A_ID');
v_url := <page_url>;
if v_id > 0 then
call(v_url||'&p_arg_names=id&p_arg_values='||v_id);
end if;
End;
In the called form in "Before displaying form" plsql section write this code.
for i in 1..p_arg_names.count loop
if p_arg_names(i) = 'id' then
p_session.set_value(
p_block_name => blk,
p_attribute_name => 'A_ID',
p_value => p_arg_values(i)
end if;
end loop;
This code picks up the value from p_arg_values and assigns it to the form field.
Hope that helps.
