How to avoid error "HTP 404" when working with "Google Suggest" and Apex 3?

Question

Hi,
I am trying to implement the GOOGLE SUGGEST function in an APEX application (a sample of Google Suggest + APEX can be found in http://htmldb.oracle.com/pls/otn/f?p=22777:6:4312817919732414 or http://teradata.weizheng.net/2009/08/using-google-suggest-in-apex.html).
The release of APEX is 3.2.1 and of RDBMS is 9.2.0.8 (64 bits). They are installed on a SOLARIS 9 SPARC 64-bits server, where i have an EBS 11.5.9 application. So, i´m using RDBMS and Apache of EBS 11.5.9 to work with APEX 3.2.1.
I can see the list generated by javascript function when i type in P2_REPORT_SEARCH, but when i SELECT an item (pressing ENTER), i have got an "HTP 404 error". Looking in the logs in the apache, i have found this error:
http://prigaudi1.sote.tasa.com.ar:8002/pls/apex/wwv_flow.accept
[Tue Jul 26 10:12:53 2011] [error] mod_plsql: /pls/apex/wwv_flow.accept ORA-0
wwv_flow.accept: SIGNATURE (parameter names) MISMATCH
VARIABLES IN FORM NOT IN PROCEDURE: AQ,OQ
NON-DEFAULT VARIABLES IN PROCEDURE NOT IN FORM:
I think that "AQ" and "OQ" are variables of "ac.js" javascript.
The JAVASCRIPT procedure that is situated on HTML HEADER of PAGE 2 is :
<script src="/i/BASE_CONOCIMIENTO/ac_google/ac.js" type="text/javascript"> </script>
<script language="Javascript" type="text/javascript">
function iac()
{ InstallAC(document.wwv_flow,document.getElementById
('P2_REPORT_SEARCH'),"","ASKTOM.incsearch_articulo","en"); }
</script>
The JAVASCRIPT function that is situated on HTML BODY ATTRIBUTE is:
onLoad="iac()"
My "INCSEARCH" procedure is described below:
CREATE OR REPLACE PROCEDURE IncSearch_ARTICULO(qu VARCHAR2, hl VARCHAR2, js VARCHAR2,
client VARCHAR2 default null) AS
l_List1 varchar2(10000);
l_Query varchar2(255);
l_separator varchar2(10) default '';
BEGIN
l_Query := qu || '%';
FOR x IN (select TIT_TOPICO,NULL AS COMPLEMENTO from BAC_TOPICO where Upper(TIT_TOPICO) like Upper
(l_Query) order by 1)
LOOP
l_list1 := l_List1 || l_separator || '"' || x.TIT_TOPICO || '"';
l_separator := ',';
END LOOP;
owa_util.mime_header('text/html', false);
owa_util.http_header_close;
htp.p('sendRPCDone(frameElement, "'|| qu ||'", new Array(' || l_List1 || '), new Array(""), new Array(""));');
END INCSEARCH_ARTICULO;
I think this procedure is working fine on Apache Server:
Example:
http://prigaudi1.sote.tasa.com.ar:8002/pls/apex/asktom.incsearch_articulo?qu=A&hl=A&js=a <enter>
sendRPCDone(frameElement, "A", new Array("Ayuda Como crear un topico en la base de conocimiento"), new Array
(""), new Array(""));
I would like to know how i can solve this problem of HTP 404 and "SIGNATURE (parameter names) MISMATCH"
Best regards,
