Vo.executeQuery() not working

Question

Hi All,
I am new to the world of OAF.I need to customize an OAF page(11i). I am trying to populate data from FND table using VO.
My VO query:
<SQLQuery><![CDATA[
select lookup_code as  skuid1,meaning as descr, null as count_1,null as serialno , tag as tag from apps.fnd_lookup_values flv
       where     lookup_type like('WWPO_FEILD_PHY_SKU_MAINTANANCE')
      AND    enabled_flag = 'Y'
      AND    NVL ( start_date_active, TO_CHAR ( SYSDATE, 'DD-MON-RRRR' ) ) <=
                                                                  TO_CHAR ( SYSDATE, 'DD-MON-RRRR' )
      AND    NVL ( end_date_active, TO_CHAR ( SYSDATE, 'DD-MON-RRRR' ) ) >=
                                                                  TO_CHAR ( SYSDATE, 'DD-MON-RRRR' )
      AND    LANGUAGE = 'US'
   ]]></SQLQuery>
I am using a region(Table) with a submitbutton:
My CO code:
  if (pageContext.getParameter("PopDetBtn") != null)
       am.invokeMethod("PopDet");
My AM code :
public void PopDet()
XXWWPopDetVOImpl popVO = getXXWWPopDetVO1();
popVO.setRangeSize(1);
popVO.setWhereClause(null);
popVO.setRangeSize(1);
popVO.executeQuery();
executeQuery() is not working.Data is not getting fetched. Please let me know where I am wrong.
This is my first object in OAF.

Hi Debanjan,
Your CO Code is like this ---
    OAApplicationModule am = pageContext.getApplicationModule(webBean);
      if (pageContext.getParameter("PopDetBtn") != null) {
        am.invokeMethod("PopDet");
And I have kept the AM Code also same.
It is working for me. Please check your VO Query and try to run that query in database and check whether the query is returning data or not.
I have used the simple query ---  " select * from emp "
If you have resolved the issue, Please let me know what changes you have made.
If you are facing any other issue, you can feel free to ask.
