Issue with VO refresh

Question

Hi,
I am creating a custom OAF page for timecard where if we change the period in update timecard mode, it should show the entries for the new period.
The VO used for showing the data for time entry is not EO based since my timecard is based on APIs provided by OTL (HRMS) module. I am calling the apis through the a db procedure called in AM. The VO is used for querying the data.
The issue description is
When I change the period, my time entry data is not reflecting the change of data. I am using an advanced table for showing the time entries and period field is a messageChoice bean for which I have fireAction property and also saying submit as true. However when I change the period in update timecard mode, it is not showing the new data but retains the data queried for first time. I have a action periodChange on message choice bean and I am calling back the same page using below code in process form request. I am trying to clear the time entry data by all possible methods but it is getting retained everytime.
if ("periodChange".equals(event)) {
OAMessageChoiceBean tperiod = (OAMessageChoiceBean) webBean.findChildRecursive("TimePeriodName");
String newStartTime = tperiod.getSelectionValue(pageContext);
pageContext.releaseAllRootApplicationModules();
am.resetState(true);
if (action.equals("Create")) {
pageContext.setForwardURL ("OA.jsp?page=/xxrpay/oracle/apps/hxc/webui/TimecardPG&ResourceType=PERSON&retainAM=N&Action=Create&StartTime="+newStartTime+"&StopTime="+stopTime+"&ResourceId="+resourceId,null, (byte)0, null, null, false, "N",OAException.ERROR);
if(action.equals("Update")){
pageContext.setForwardURL ("OA.jsp?page=/xxrpay/oracle/apps/hxc/webui/TimecardPG&ResourceType=PERSON&retainAM=N&Action=Update&Timecard_id="+tcId+"&StartTime="+newStartTime+"&StopTime="+stopTime+"&TimecardApprovalStatus="+pageContext.getParameter("TimecardApprovalStatus")+"&ResourceId="+resourceId,null, (byte)0, null, null, false, "N",OAException.ERROR);
I have even tried cancelling the VO query and clearing the AM, advanced table as well as VO cache.
Thanks,

Kumar,
I have a similar need and I apologize upfront that I am new to OAF (and Java). :(
Basically, when I return to the search page from viewing details, the previous search is saved and cannot be cleared without going home and coming back in.
I know that Vo.clearcache(); is the solution.
So, I need to add this to the processRequest method in the CO of my search page... which does not have a direct reference to the VO.
How do I set Vo in this case?
