Urgent: Issue with Dynamic VO Query in LoV

Question

Hi All,
We have created an LoV based on a Vo. We have put a dummy query initially and are trying to change the VO query at run time.(using vo.setQuery method). But surprsingly LoV display is still as per static query.And when I do vo.getAllRowsInRange and see the actual values the results are as per the
Dynamic query.
Basicall I want to kniw:
Is it possibble to change the entire VO query dynamically and use that in LoV? But its working perfectly fine outside LoV .
Apprecite quick reponnce in this.
Thanks

Thank You,
Below is a method in AM for whcich the LoV and VO are associated. This method gets trigeered from LoV controller.
public void initVo()
String http="http://schemas.xmlsoap.org/soap/envelope/";
String qry=" select * from( SELECT "+
"extract(value(p),'//altContactName/text()','xmlns:soap="+http+"').getStringval() one "+
",extract(value(p),'//customerNumber/text()','xmlns:soap="+http+"').getStringval() two "+
",extract(value(p),'//csystemDescription/text()','xmlns:soap="+http+"').getStringval() three "+
",extract(value(p),'//itemClass/text()','xmlns:soap="+http+"').getStringval() four "+
" FROM TABLE(XMLSEQUENCE("+
" EXTRACT"+
" (Pkg.proc('aaaaa'),'//result')"+
" )"+
" ) p)";
lovVO2Impl vo =getlovVO2_1();
vo.setQuery(qry);
vo.setMaxFetchSize(-1);
vo.setWhereClause(null);
vo.setWhereClauseParams(null);
vo.executeQuery();
//vo.setRangeSize(-1);
//vo.executeQuery();
Row[] rows=vo.getAllRowsInRange();
System.out.println("Lenght:"+rows.length);
for(int rowIndex = 0; rowIndex < rows.length; rowIndex++)
String one = (String)rows[rowIndex].getAttribute("One");
String two = (String)rows[rowIndex].getAttribute("Two");
System.out.println("One:"+one);
System.out.println("Two:"+two);
System.out.println("in vo.getQuery:"+vo.getQuery());
One more thing i noticed is, if i dont add any filtering criteria and direclty click 'Go' its woeking fine, i.e getting values from the dynamic query.
But if i add some filtering criteria like '%' its using the static query and binding the filtering criteria to that query rather than dynamic query.
Thanks in advance
