GReturn get.get('XML') issue (Roel)

Question

Roel,
I have an issue with the "function call LOV onchange" (I have the same issue with autocomplete function od Denes)
The first alert in the source below return the value of my item and it is send to the function but the second alert return '0', no result found
if(pValue){
get.add('TEMPORARY_APPLICATION_ITEM',pValue)
alert(pValue);
}else{
get.add('TEMPORARY_APPLICATION_ITEM','null')
gReturn = get.get('XML');
alert(gReturn.getElementsByTagName("item").length);
When i execute the same function in SQL commands i have
Content-type: text/xml; charset=UTF-8
Cache-Control: no-cache
Pragma: no-cache
this xml genericly sets multiple items5EcarZb23
Statement processed.
U can see that a record is found for the id sent to the function.
Could u help me? thx

Hi Celio,
Sorry for the late response.
ODP is the On Demand Process
From the JavaScript you make a call to a ODP procedure you need to create in the Shared Components.
I like to use alert(myvariable); etc in my Javascript to see that values are getting to the ODP call.
Then because the ODP is all PL/SQL I like to place a few insert statements to a table that I created called bcdebug.
These inserts shows it actually got to the ODP and it is not a JavaScript problem.
Then I would insert again to show the value for v('TEMPORARY_APPLICATION_ITEM') in the ODP also.
I created a procedure called pdebug so I could debug my PL/SQL code.
create or replace PROCEDURE "PDEBUG"
(pinput IN VARCHAR2,
pcommit IN BOOLEAN DEFAULT TRUE)
is
lString VARCHAR2(4000);
lstart NUMBER;
lLength NUMBER;
lcnt NUMBER:=0;
BEGIN
--htp.p('PDEBUG['||length(pinput)||']');
lLength:=length(pinput);
lstart:=1;
LOOP
lcnt:=lcnt + 1;
lString:=substr(pinput,lstart,4000);
-- htp.p('PDEBUG-Length['||lLength||']');
-- htp.p('PDEBUG-Start['||lstart||']');
insert into bcdebug
(input, create_dttm)
values
(lString,sysdate);
lLength:=lLength - 4000;
lstart:=lstart + 4000;
EXIT WHEN lLength <= 0 OR lcnt >10;
END LOOP;
if(pCOMMIT)then
COMMIT;
end if;
END;
pdebug('In Get select List');
pdebug(v('TEMPORARY_APPLICATION_ITEM ');
Hope it helps for future coding too.
