Problem with APEXT_ITEM.SELECT_LIST_FROM_QUERY in Apex 4.0.1

Question

Hi ,
In my Interactive Report I have One Column like ..
,APEX_ITEM.SELECT_LIST_FROM_QUERY(3,LR_NAME,'select table_name from all_synonyms where owner = ''MJP_APPLICATION'' and substr(table_name,1,2) not in (''FN'',''SP'',''SE'',''P_'') ') LR_NAME
but it showing following Error message when I run the page(inner query returning 75 Row's)
ORA-06502: PL/SQL: numeric or value error: character string buffer too small+_
If I put limit on the number of rows of select list like ..
,APEX_ITEM.SELECT_LIST_FROM_QUERY(3,LR_NAME,'select table_name from all_synonyms where owner = ''MJP_APPLICATION'' and substr(table_name,1,2) not in (''FN'',''SP'',''SE'',''P_'') and rownum < 25 ') LR_NAME
then its working fine may I know what is the reason
thanks & regards,

Actually I am adding new row with the help of Union Query
see the query
select
     SCHEDULE_ID DELETE_TRANSACTION
, APEX_ITEM.RADIOGROUP(1,SCHEDULE_ID,:P9_X,'','onClick="highlightrow(this)" ') as "--"
,APEX_ITEM.HIDDEN(1,'U')|| APEX_ITEM.HIDDEN(2,SCHEDULE_ID) "-"
*,APEX_ITEM.SELECT_LIST_FROM_QUERY_XL(4,EMP_NO,'select emp_name,emp_no*
from gen_employee') "EMP_NO"
,APEX_ITEM.TEXT(5,PURPOSE,40,40) "PURPOSE"
,APEX_ITEM.TEXT(6,SCHEDULE_FLAG,2,2) "FLAG"
,APEX_ITEM.TEXT(7,TOTAL_AMOUNT) "TOTAL_AMOUNT"
FROM mjp_paybill.pay_schedule_main
union
select NULL DELETE_TRANSACTION
, APEX_ITEM.RADIOGROUP(1,null,:P9_X,'','onClick="highlightrow(this)" ') as "--"
,APEX_ITEM.HIDDEN(1,'I') || APEX_ITEM.HIDDEN(2,NULL) "SCHEDULE_ID"
*,APEX_ITEM.SELECT_LIST_FROM_QUERY_XL(4,NULL,'select emp_name,emp_no from gen_employee') "EMP_NO"*
,APEX_ITEM.TEXT(5,NULL,40,40) "PURPOSE"
,APEX_ITEM.TEXT(6,null,2,2) "FLAG"
,APEX_ITEM.TEXT(7,NULL) "TOTAL_AMOUNT"
from dual
WHERE :P9_HIDDEN IS NOT NULL
ORDER BY 1 DESC
