Does APEX re-write output HTML from an application process

Question

I have a process which has the following line
htp.prn('<input type="hidden" name="F05" value="' || l_submitted_previously || '"/>');this however is outputting the following html
<input name="F05" value="N" type="hidden">as you can see the parameters in the tag are not in the order I specified and also the closing slash is omitted.
Can anyone explain this?

Answer 1

APEX 3.2.1.00.12
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
Unfortunately I doh't know the web server architecture
Firefox v13
Custom theme
Custom templates
Hidden item
I don't think the last 4 items listed above will have a bearing on this because it's a dynamically produced item created by an application process. I have pasted the entire code for the process in case that helps.
DECLARE
     l_year_passed number := wwv_flow.g_x01;
     l_expenditure_value number;
     l_submitted_previously varchar2(1) := 'N';
BEGIN
     SELECT DECODE(COUNT(*),0,'N','Y')
     INTO l_submitted_previously
     FROM F_EXPENDITURE
     WHERE FINANCIAL_YEAR_KEY = l_year_passed;
    for rec in (SELECT *
                FROM l_service_group
                WHERE service_designated_year<=l_year_passed
                AND service_designated_year>0
                order by NON_SERVICE_GROUP_FLAG, SERVICE_GROUP_SHORT_NAME)
     loop
     BEGIN
          SELECT EXPENDITURE_VALUE
          INTO l_expenditure_value
          FROM F_EXPENDITURE
          WHERE FINANCIAL_YEAR_KEY = l_year_passed
          AND SERVICE_GROUP_KEY = rec.SERVICE_GROUP_KEY;
          EXCEPTION
          WHEN NO_DATA_FOUND THEN
          l_expenditure_value := NULL;
     END;
          htp.prn('<tr><td><label for="F01_' || rec.SERVICE_GROUP_KEY || '"><span class="t13RequiredLabel"><img src="/i/requiredicon_status2.gif" alt="">' || rec.SERVICE_GROUP_SHORT_NAME || '</span></label></td><td><input type="text" name="F01" id="F01_' || rec.SERVICE_GROUP_KEY || '" value="'||l_expenditure_value||'"/><input type="hidden" name="F02" id="F02_' || rec.SERVICE_GROUP_KEY || '" value="' || rec.SERVICE_GROUP_KEY || '"/></td></tr>');
     end loop;
     if l_year_passed = 0 then
          htp.p('<p>Please select a financial year</p>');
     end if;
     htp.prn('<input type="hidden" name="F05" value="' || l_submitted_previously || '"/>');
END;
