OA Query Region shows previous search results when moving between pages

Question

Hello All,
I have a custom OA Page which has a query region based on a LOV for searching device names. The problem I am facing is once device name is searched and I go to another page through the quick links and come back to same Search Device page, it shows the previous searched results. I am not retaining AM for any page navigation.
Things I have already tried :
1 . I have tried refreshing VO by using clearcache and reset methods on VO.
2. Get the Go button from the query region in ProcessFormRequest and on Go button click I use forwardImmediatelyToCurrentPage. And in Process Request method I am querying the results manually when Go button is clicked. Otherwise I am manually making the where clause condition 1=2 and ensuring that the VO does not return any rows.
But still I am not able to get rid of the issue.
The code used is pasted below for your reference. It is urgent. Can you please provide any pointers.
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
try
VpaAdminAMImpl am = (VpaAdminAMImpl)pageContext.getApplicationModule(webBean);
TkvpaDeviceSearchVOImpl deviceAll = am.getTkvpaDeviceSearchVO1();
deviceAll.clearCache();
deviceAll.reset();
deviceAll.setWhereClause("1=2");
deviceAll.setWhereClauseParams(null);
String query = deviceAll.getQuery();
System.out.println("getSearchResult query :="+query);
deviceAll.executeQuery();
OAQueryBean queryBean = (OAQueryBean)webBean.findChildRecursive("region1");
String goAction = queryBean.getGoButtonName();
if(pageContext.getParameter(goAction) != null)
getSearchResult(am, pageContext, webBean);
catch(Exception ex)
throwException("SearchDeviceCO.processRequest",ex);
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
String action = pageContext.getParameter(EVENT_PARAM);
OAQueryBean queryBean = (OAQueryBean)webBean.findChildRecursive("region1");
String Go = queryBean.getGoButtonName();
System.out.println(pageContext.getParameter(Go));
if(pageContext.getParameter(Go) != null)
pageContext.forwardImmediatelyToCurrentPage(null,false,"N");
public void getSearchResult(VpaAdminAMImpl am, OAPageContext pageContext, OAWebBean webBean)
try
String device = pageContext.getParameter("deviceSearch");
StringBuffer sb = new StringBuffer();
if(device != null && device != "")
sb.append(" DEVICE_NAME = '");
sb.append(device);
sb.append("'");
String sql = sb.toString();
TkvpaDeviceSearchVOImpl deviceAll = am.getTkvpaDeviceSearchVO1();
deviceAll.setWhereClause(sql);
deviceAll.setWhereClauseParams(null);
String query = deviceAll.getQuery();
System.out.println("getSearchResult query :="+query);
deviceAll.executeQuery();
}catch(Exception e)
e.printStackTrace();

Hi Anand,
The getSearchResult method also does the same thing. I have also tried to remove the dependency on getSearchResult and wrote the same code in ProcessRequest() but still it does not solve the problem.
In fact, I have ensured that the VO does not contain any records and have checked these by using SOPs and debug in JDEV. The interesting point is the VO does not have any records but still the previous search data and search criteria is shown when we navigate to the page. Printed the query just before performing execute query and that query does not return any records. Also tried printing something if there are any records in the VO by using vo.hasNext().
Data gets stored somewhere and it is shown when the page is navigated from other page. FYI, this page is accessed from quick links and there are other pages also in the quick links and when we navigate between these pages we get to see the previous search results. Tried methods clearCache(), reset() on VOs but still unsuccessful.
Not even that I thought that the VO may be corrupted in some sense so I created a new VO instance in the AM and then used newly created VO instance in the query region. But still no luck.
Any pointers will be appreciated.
Thanks in Advance,
Abhishek
