Added records in DB are not show in page until start a new browser

Question

I am inserting a record in my DB table by writing a code in my App Module Impl class. The code is shown below:
EntityDefImpl productDef = ActivitySubtype_EOImpl.getDefinitionObject();
ActivitySubtype_EOImpl newSubActivityType = (ActivitySubtype_EOImpl)productDef.createInstance2(getDBTransaction(),null);
newSubActivityType.setAttribute("SubActivityName",subActivityType);
getDBTransaction().commit();
getDBTransaction().clearEntityCache(null); // Here I have tried lot of other function like refresh(), setClearCacheOnCommit() but noting works.
For updating the cache I have tried many functions but nothing is working. I mean that I when I go to the same browser and view the rows, the row is added but without any PK (which is being generated by a sequence fired by trigger in my DB), until I start a new browser to see the record. When I start a new browser and view the rows I can see everything in sync with the DB table. Can someone let me know how to update the View Object cache?
Appreciate your kind help.
Thanks,
Sanjay

Hello John,
Many thanks for your reply. I have marked the configuration you have talked about, but still it does not work.
I understand that the problem is that my VO cache is not getting updated on its own. When I open a new browser, for this new session when the SQL query gets fired, the VO cache gets updated from the DB and the changes are visible in the new page.
To overcome this problem I tried adding row using my VO (and not EO, as in my previous case). But I am getting some NullPointerException in that.
Here is the code and exception.
Code:
String amDef = "model.activity.subtype.Second_AMImpl";
String config = "Second_AMLocal";
ApplicationModule secondAM = Configuration.createRootApplicationModule(amDef, config);
ActivitySubType_VOImpl svcReqs = (ActivitySubType_VOImpl) secondAM.findViewObject("ActivitySubType_VOImpl");
if(svcReqs != null)
System.out.println("I am NOT NULL");
else
System.out.println("I am NULL"); // This object is null
Row newSvcReq = svcReqs.createRow();
svcReqs.insertRow(newSvcReq);
Exception:
javax.faces.FacesException: #{backing_addSA.create_action}: javax.faces.el.EvaluationException: java.lang.NullPointerException     at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:98)

My VO is in the same package, hence for the VO I not mentioned the package. When I mentioned the package it not able to create the VO at all.
Can you help me on creating a new record using a VO?
Thanks,
Sanjay
