How to supply values for searchCriteria items in af:query programmatically

Question

Hi,
Is it possible to supply the default values for search criteria items in af:query programmatically? I didn't find any of the method to set the values for the search criteria items inside the oracle.adf.view.rich.model.Criterion and oracle.adf.view.rich.model.AttributeCriterion classes.
Please let me know how can I supply DATE values by default for the search criteria items inside the view criteria.
Thanks

Jdev I am using is 1.5.
I've search page where I've a date field (like TransactionDate). The transactionDate is a transient variable in my VO. Created a view criteria using this transient date filed and kept the operator as 'Between'. When I load the page, I want to keep the values for Between operator as 'CurrentDate' and 'CurrentDate - 365 days' (LastYearDate as of today).
I can't use bind variables to set the currentDate and lastYearDate to the values of the 'Between' operator. If I use so, I will get an error 'Attempt to set a parameter that doesn't occur in the sql.....'.
So I thought of overriding the QueryEvent inside the bean. But I didn't find a way to set the values for the TransactionDate programmatically.
I tried below code in the queryEvent method, but in this case the response time is very hign ( I didn't see the result till 30mn).
DCBindingContainer bc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
ViewCriteria vc =
JUSearchBindingCustomizer.getViewCriteria((DCBindingContainer)bc.findExecutableBinding("SupplierSearchCriteriaQuery"),"__ImplicitViewCriteria__");
Date curretYearDate = null, lastYearDate = null;
Calendar calendar = Calendar.getInstance();
curretYearDate = calendar.getTime();
calendar.add(Calendar.DAY_OF_YEAR, -365);
lastYearDate =calendar.getTime();
Object o = new Date();
ViewCriteriaRow vcr = (ViewCriteriaRow)vc.get(0);
for(int i=0;i<vcr.getAttributeNames().length;i++) {
if(vcr.getAttributeNames() == "LastTransactionDate") {
System.out.println("====================== opeartor ================== " + vcr.getOperator("LastTransactionDate"));
if( ("%".equals(vcr.getAttributeValues()[i]) || vcr.getAttributeValues()[i]==null)) {
List nameList = new ArrayList();
nameList.add("LastTransactionDate");
List valueList = new ArrayList();
valueList.add(lastYearDate);
valueList.add(curretYearDate);
vcr.setAttributeValues(nameList, valueList);
vc.addRow(vcr);
JUSearchBindingCustomizer.applyAndExecuteViewCriteria(bc, vc);
