Manually Created Tabular Forms and Firefox 4 Problem

Question

I have a tabular form created with pl/sql dynamic content regions using the apex_item toolkit. An apex collection is used to maintain state for the tabular data entered. It is an application originally created in APEX 1.5 and upgraded through the years to 3.2 . Never a problem with the application until now. I have re-created the issue on the apex.oracle.com site here:
http://apex.oracle.com/pls/apex/f?p=28213
Run the application in IE ( I am using 8) and then run in Firefox 4. Enter a quantity in the first item then hit Next and then Previous multiple times. See the problem? The problem does not occur in FF 3.6 or Chrome either. I have not tried Safari as my mac is at home and I am at the office.
Here is code for both pl/sql regions and the collection update (after submit). Page 2 is just a report selecting from the collection. I have spent a day trying to solve this problem. Any help will be appreciated. Re-architecting without the pl/sql dynamic regions is not an option at this time.

Report region 1: (collection not exists)
declare
other1 varchar2(2000) default null;
other_char varchar2(32000) default null;
begin
htp.p('<table border="1" width="100%">');
htp.tablerowopen;
htp.p('<th>Description</th><th>Price</th><th>Quantity</th>');
htp.tablerowclose;
for rec in (SELECT id, description,to_char(price,'$9,999.99') price
FROM foodbev_items order by id) loop
select apex_item.hidden(1,rec.id) into other_char from dual;
htp.p(other_char);
select apex_item.hidden(3,rec.description) into other_char from dual;
htp.p(other_char);
htp.tablerowopen;
htp.tabledata(rec.description);
htp.tabledata(rec.price,'right');
-- quantity here
select apex_item.text(6,null,5)
into other1 from dual;
htp.tabledata(other1);
htp.p('<tablerowclose>');
end loop;
htp.p('</table>');
end;
Report Region 2: (collection exists)
declare
other1 varchar2(2000) default null;
other_char varchar2(32000) default null;
begin
htp.p('<table border="1" width="100%">');
htp.tablerowopen;
htp.p('<th>Description</th><th>Price</th><th>Quantity</th>');
htp.tablerowclose;
-- collection BREAKFAST_SELECTION
-- 1 is item_id, 3 is descrip 6 is qty
for rec in (SELECT a.c001 item_id, a.c003 description,to_char(b.price,'$9,999.99') price, a.c006 entered_qty
FROM htmldb_collections a, foodbev_items b where a.c001 = to_char(b.id) and a.collection_name = 'BREAKFAST_SELECTION' order by b.id) loop
select apex_item.hidden(1,rec.item_id) into other_char from dual;
htp.p(other_char);
select apex_item.hidden(3,rec.description) into other_char from dual;
htp.p(other_char);
htp.tablerowopen;
htp.tabledata(rec.description);
htp.tabledata(rec.price,'right');
-- quantity here
select apex_item.text(6,rec.entered_qty,5,5)
into other1 from dual;
htp.tabledata(other1);
htp.p('<tablerowclose>');
end loop;
htp.p('</table>');
end;
Collection Update:
declare
la_cks wwv_flow_global.vc_arr2;
other_char varchar2(2000) default null;
other_char1 varchar2(2000) default null;
begin
htmldb_collection.create_or_truncate_collection('BREAKFAST_SELECTION');
for i in 1 .. htmldb_application.g_f01.count
loop
-- 1 is item_id, 2 is numeric price , 3 is descrip, 6 is qty
htmldb_collection.add_member(
p_collection_name => 'BREAKFAST_SELECTION',
p_c001 => htmldb_application.g_f01(i),
p_c003 => htmldb_application.g_f03(i),
p_c006 => htmldb_application.g_f06(i)
end loop;
end;

Dave,
All I am saying is both of your report regions can very easily be made into a sql statement and put into a report region. you can then use the apex builder to format them. How you validate that data is up to you and would not change all that much other than making sure your global arrays are pointing to the same columns. it just looks to me that you are going through a lot more effort to not use what apex will very easily do for you. Plus the more apex built in functionality you use the more robust your application will be in different browsers.
I tried running your application in IE 7 and FF 3.6 and i did not see any problems. i entered 1,6,4 clicked next. Clicked previous numerous times and was redirected back to the page and saw 1,6,4.
What is happening when you run the app?
Thanks,
