View Links for Programmatic View Objects

Question

Hi All,
I created a read only VO called MyVO based on a sql query.
I created 2 programmatic view objects, MasterView and ChildView.
In a custom method in AMImpl class ,I iterate through this MyVO resultset and get the rows in a Row object.
Based on some attributes values of the Row, I populate both master and child View Objects.
I have created a view link between Master and Child Programmatic View Objects and have exposed them in AM.
Now I run the AM, and run the method exposed in client interface.
Now I click on my master and child programmatic views.
I see that the rows are populated in both of these programmatic VOs.
But when I click on viewlink which I have exposed under master, it doesnt show me any
record for child.
This is my method of AMImpl which is exposed in AM client interface.
public void constructLines(){
ViewObject vo= this.getMyVO1();
ViewObject master=this.getTransientVO1();
ViewObject child=this.getTransientLineVO1();
Row r,masterRow,childRow;
int count=0;
while(vo.hasNext()){
++count;
r=vo.next();
masterRow = master.createRow();
if(r.getAttribute("QuoteHeaderId")!=null)
masterRow.setAttribute("QuoteHeaderId",
r.getAttribute("QuoteHeaderId").toString());
if(r.getAttribute("QuoteLineId")!=null)
masterRow.setAttribute("QuoteLineId",
r.getAttribute("QuoteLineId").toString());
if(r.getAttribute("LineNumber")!=null)
masterRow.setAttribute("LineNumber",
r.getAttribute("LineNumber").toString());
master.insertRow(masterRow);
childRow= child.createRow();
if(r.getAttribute("RefLineId")!=null)
childRow.setAttribute("RefLineId",
r.getAttribute("QuoteLineId").toString());
if(r.getAttribute("QuoteHeaderId")!=null)
childRow.setAttribute("QuoteHeaderId",
r.getAttribute("QuoteHeaderId").toString());
child.insertRow(childRow);
This is stopping me from my development progress.
Any suggestion to solve this will be of great help.
Thanks,

Hi..
have you define relationship correctly between masterVO and childVO.sometime there may be the problem.
