Bug in Listener 1.0.2

Question

Hi
we got still a lot of (reproducible!!) errors which the new listener and XE / APEX 4.0:
This is in the log file:
p:1000:300:3002970452069172::::P300_REPORT_ID:272PAGE CALL:
declare
nlns number := 999999;
l_clob CLOB;
lines htp.htbuf_arr;
l_buff varchar2(32767);
l_clob_init boolean:= false;
l_file varchar2(5);
begin
OWA.GET_PAGE(lines, nlns);
if (nlns > 1) then
for i in 1..nlns loop
if ( length(lines(i)) > 0 ) then
if ( ( lengthb(l_buff) + lengthb(lines(i))) > 32767) then
if (NOT l_clob_init) then
dbms_lob.createtemporary(l_clob, TRUE);
dbms_lob.open(l_clob, dbms_lob.lob_readwrite);
l_clob_init:=true;
end if;
dbms_lob.writeappend(l_clob,length(l_buff),l_buff);
l_buff := lines(i);
else
l_buff := l_buff || lines(i);
end if;
end if;
end loop;
end if;
if (l_clob_init) then
dbms_lob.writeappend(l_clob,length(l_buff),l_buff);
l_buff := '';
end if;
? := l_clob;
? := l_buff;
if (wpg_docload.is_file_download) then l_file:='TRUE'; else l_file := 'FALSE'; end if; ? := l_file;
end;

The interesting thing is: if we reduce the query result by just one row (the original report has only 8 lines and about 2000 Bytes in total, so it isn't a very huge result set!!!!) everything works fine. Or you can add just one column "null as dummy" and again - no problems. My first idea was that the exact amount of bytes in the result set causes this error. So I modified my query by adding some characters like this "select col1||'XYZ', col2,col3 from ....", but it didn't help, but "select col1, col2,col3, null as dummy from ..." helps!
Really strange! I think it has to do with the (new?) OWA.GET_PAGES function but I've no idea how to handle this.
Urgent help is needed!
Regards
Joachim

Hi,
here is another thread about it: http://kr.forums.oracle.com/forums/thread.jspa?messageID=4548821
It talks about it is a language related problem. I didn't found it anywhere else, so maybe make a SR with Oracle Support.
