Extending a View Object

Question

Hello,
Which is the best way to extend a view object and change the where clause?
i am customizing sourcing module, at the search suppplier option in the negotiation tab
I create a new Controller, and i change the standard controller to the button.
I can only get the query itself but not the where to modify.
suppliersearchvoimpl.setWhereClause("pv.vendor_name = :1");
suppliersearchvoimpl.setWhereClauseParams(null);
suppliersearchvoimpl.setWhereClauseParam(0,"AUTO HAUS");
     suppliersearchvoimpl.executeQuery();
I use that, but it is not working.
The standard class has a dynamic query.
Thanks

aj,
take a look at this
when i press the Search button, i am not getting anything
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
OAApplicationModule am = (OAApplicationModule)oapagecontext.getApplicationModule(oawebbean);
                              SupplierSearchVOImpl vo = (SupplierSearchVOImpl)am.findViewObject("SupplierSearchVO");
                         try
vo.setWhereClause("pv.vendor_name = :1");
vo.setWhereClauseParams(null);
vo.setWhereClauseParam(0,"AUTO HAUS");
vo.executeQuery();
catch(Exception exception1)
System.err.println(exception1 + " getting vendor category select");
//super.processFormRequest(oapagecontext, oawebbean);
thanks
