Read-Only view object won't give me it's row

Question

Hi,
I have a read only view object which when executed has one row in it, but the next method returns null.
this is my code in the AM:
    public Row getPerson() {
        Row row = null;
        ViewObject vo = getPersonsView1();
        vo.setNamedWhereClauseParam("p_login_id", getUserPrincipalName());
        vo.executeQuery();
        System.out.println("rows:" + vo.getEstimatedRowCount());
        if (vo.hasNext())
           row = vo.next();
        return row;  
    }and the console log:

Source breakpoint occurred at line 38 of SystemServiceImpl.java.Note above System.out.println("rows:" + vo.getEstimatedRowCount()); returns:
06/09/15 10:38:00 rows:1
but when i debug with a break point in the above method if (vo.hasNext()) returns false.
I have tried doing row = vo.next(); without the if statement, but row still evaluates to null.
The VO returns one record in the BC4J tester and I have this exact method and VO defined in another project and it works there. Tearing my hair out with this one...

try RowSetIterator instead,
RowSetIterator it = vo.createRowSetIterator("myIt");
if(it.hasNext())
MyVORowImpl row = (MyVORowImpl)it.next()
//don't forget close the RowSetIterator
I guess you use the VO.next(), but the current row of the VO is the one you get from db, and his next is null...
