Pages loose item persistence in frames

Question

I have these pages that branch to each other. This works fine, except when the HTMLDB pages are part of an intranet app and actually rendered inside a frame. When this happens, then my page cache is cleared even though I do not explicitly clear it with the URL argument. They transition to the correct pages within the frame, just the items are now cleared.

Answer 1

The pages are public. I am using this code to process an insert and then return to the calling previous page:
declare
l_items varchar2(4000);
l_values varchar2(4000);
begin
if :REQUEST = 'CREATE_NEW' then
insert into hr.dwh_discussion(parent_id,subject,topic_text,author,category)
values (:P26_PARENT_ID,:P26_SUBJECT,:P26_TEXT,:P26_AUTHOR,:P26_CAT);
htmldb_application.g_page_text_generated := true;
case :P26_RETURN_PAGE
when '22' then
owa_util.redirect_url('f?p=110:22::::26');
when '23' then
l_items := 'P23_ID,P23_ID_STATIC,P23_CONTENT_ID';
l_values := :P26_ID_STATIC||','||:P26_ID_STATIC||','||:P26_PARENT_ID;
owa_util.redirect_url('f?p=110:23::::26:'||l_items||':'||l_values);
else
null;
end case;
end if;
end;
If I leave out the items/values list from the URL, then page 23 will clear all its items when these pages are in a frame. If I leave off the items/values from the URL but the pages are on top, not in a frame, then the page 23 items are not cleared.
I transition to page 26 from page 23 with these items/values in the URL:
items - P26_SUBJECT,P26_PARENT_ID,P26_RETURN_PAGE,P26_ID_STATIC
values - re - &P23_SUBJECT.,&P23_CONTENT_ID.,23,&P23_ID_STATIC.
I am using a custom LDAP authentication scheme that makes a call to a PL/SQL function:
return hr.util_ldap.connectAuthenticate;
function connectAuthenticate(p_username in varchar2,p_password in varchar2)
return boolean
as
l_retval PLS_INTEGER := -1;
l_ssl PLS_INTEGER := -1;
l_session DBMS_LDAP.session;
l_attrs DBMS_LDAP.string_collection;
begin
DBMS_LDAP.use_exception := false;
begin
--connect to LDAP and authenticate
l_session := DBMS_LDAP.init(hostname => g_host,
portnum => g_port);
exception
when others then
null;
end;
l_retval := DBMS_LDAP.simple_bind_s(ld => l_session,
dn => g_pre||p_username||','||g_ldap_user_base,
passwd => p_password);
if l_retval = 0 then
-- Disconnect from the LDAP server.
l_retval := DBMS_LDAP.unbind_s(ld => l_session);
return true;
else
return false;
end if;
exception
when others then
return false;
end connectAuthenticate;
