Multirow Update with checkboxes

Question

Hi all,
I have created a page with checkboxes referencing the database columns.
The End User can only update the rows.
The database values will be correct shown, but when I will update the values I get error message: "No data found".
There is the Region code:
=======================
declare
v_query varchar2(32767);
v_where varchar2(4000);
begin
v_query := 'select td.id, apex_item.hidden(3,tm.id) master_id, tm.col1, tm.col2, apex_item.checkbox(1, td.flag1, decode(td.flag1, ''YES'',''CHECKED'', null)) flag1, apex_item.checkbox(2, td.flag2, decode(td.flag2, ''YES'', ''CHECKED'', null)) flag2 from test_master tm, test_detail td ';
if :P1_PARAMETER is not null then
v_where := ' where td.master_id = tm.id and td.id like :P1_PARAMETER';
else
v_where := ' where td.master_id = tm.id';
end if;
v_query := v_query || v_where;
return v_query;
end;
=======================
The code of update process:
=======================
for i in 1..apex_application.g_f01.count loop
update test_detail
set flag1 = apex_application.g_f01(i),
flag2 = apex_application.g_f02(i)
where id = apex_application.g_f03(i);
end loop;
=======================
I have tested it with text fields. And get no errors...
Is the multirow update with checkboxes supported?
There is the application:

Hi,
what do you mean under save "primary key"?
the following does not solve the problem too:
Process code:
=======================
declare
v_id1 number;
v_id2 number;
v_flag1 varchar2(3);
v_flag2 varchar2(3);
begin
for i in 1..apex_application.g_f03.count loop
v_flag1 := substr(apex_application.g_f01(i),1,instr(apex_application.g_f01(i),'~',1,1)-1);
v_id1 := substr(apex_application.g_f01(i),instr(apex_application.g_f01(i),'~',1,1)+1);
v_flag2 := substr(apex_application.g_f02(i),1,instr(apex_application.g_f02(i),'~',1,1)-1);
v_id2 := substr(apex_application.g_f02(i),instr(apex_application.g_f02(i),'~',1,1)+1);
update test_detail
set flag1 = apex_application.g_f01(v_flag1),
flag2 = apex_application.g_f02(v_flag2)
where id = apex_application.g_f03(i);
end loop;
end;
========================
for query like
v_query := 'select td.id, apex_item.hidden(3,tm.id) master_id, tm.col1, tm.col2, apex_item.checkbox(1, td.flag1||''~''||tm.id, decode(td.flag1, ''YES'',''CHECKED'', null)) flag1, apex_item.checkbox(2, td.flag2||''~''||tm.id, decode(td.flag2, ''YES'', ''CHECKED'', null)) flag2 from test_master tm, test_detail td ';
