How can I see changes in table with insertrow();postchanges()without commit

Question

Hi friends;
I use jdeveloper 10.1.3.1 with jheadstart 10.1.3.1.
I create two view object.In the first page I create table with one view object.
In the second page I create table (with tableselectmany) with other view.
I select many rows in second page and in the managed bean,
I insert selectted rows atributes to first pages tables attributes.
I use this code.
public String commandbuttonaction(){
CoreTable table = this.getTable1();
Set rowSet = table.getSelectionState().getKeySet();
Iterator rowSetIter = rowSet.iterator();
BindingContainer bindings = getBindings();
DCIteratorBinding pr_dcib = (DCIteratorBinding)
bindings.get("DeptIterator");
int i=206;
while (rowSetIter.hasNext()){
Key key = (Key) rowSetIter.next();
pr_dcib.setCurrentRowWithKey(key.toStringFormat(true));
RowImpl prRow = (RowImpl) pr_dcib.getCurrentRow();
String AM="model.AppModule";
String CF="AppModuleLocal";
ApplicationModule empSvc = Configuration.createRootApplicationModule(AM, CF);
ViewObject emps = empSvc.findViewObject("EmpsView1");
Row newEmp = emps.createRow();
newEmp.setAttribute("Manager",new Number(1));
newEmp.setAttribute("Department",new Number(1));
newEmp.setAttribute("Depno",new Number(3));
emps.insertRow(newEmp);
try {
newEmp.validate();
catch (Exception ex) {
System.out.println("validate catch");
try {
empSvc.getTransaction().postChanges();
catch (Exception ex) {
System.out.println("post catch");
Configuration.releaseRootApplicationModule(empSvc,true);
i=i+1;
In this code I only postchanges() in first view and dont want to commit.
But I cant see changes row in the page .If I press save I see transaction completed succesfully message.
But in database not insertted any rows.
If I write commit() after postchanges() code I see rows in the table .But I dont want to commit.Only post
my changes and if necessary I press save button in page.
How can I see changes in the page without commit???Thanks for all....

You should NEVER use statements like this in managed beans:
ApplicationModule empSvc = Configuration.createRootApplicationModule(AM, CF);
This will create a separate application module instance, not shared by the the web pages. That's why you do not see the changes.
Instead, you can use the following code:
ApplicationModule am = (ApplicationModule)JsfUtils.getExpressionValue("#{data.MyAppModuleDataControl.dataProvider}");
where MyAppModuleDataControl shoud be replaced with the name of your am data control.
