Problem with showing more then one report in loop!

Question

Hi!
In my form i have loop like
for i in 0..l_tab.count loop
multi_choise.g_izpis := l_tab(i);
execute_trigger('key-print');
end loop;
in key-print trigger i have something like this
case multi_choise.g_izpis
when 1 then
mbf_reports.run_report_web('test1.rep',
p_other_prms=>'p_id=' || :users.user_id)          
when 2 then
     mbf_reports.run_report_web('test2.rep',
p_other_prms=>'p_id=' || :users.user_id);
when 3 then
     mbf_reports.run_report_web('test3.rep',
p_other_prms=>'p_id=' || :users.user_id);
end case;
in procedure mbf_reports.run_report_web is the built-in web.show_document.
In my form i have a box with multi choise option. If i chose all of three it opens three windows but sometimes shows me test1 and 2 times test3.
If i only put message like
for i in 0..l_tab.count loop
multi_choise.g_izpis := l_tab(i);
message('something');
execute_trigger('key-print');
end loop;
it works perfectyl. I wonder why?
