Keeping current record after refreshing iterator (iterator refresh)

Question

Greetings,
I'm using the following code to refresh a master iterator, so that when data is saved\edited it is automatically refreshed in the user interface. I'm using BC for the model layer.
public String commandButton_save_action() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("Commit");
OperationBinding operationBinding2 =
bindings.getOperationBinding("Execute");
System.out.println("Now @ Global bean ... going to ...");
operationBinding.execute();
operationBinding2.execute();
// It should be a error page
if (!operationBinding.getErrors().isEmpty()) {
return null;
// Refresh main view object
DCBindingContainer bc =
(DCBindingContainer)FacesContext.getCurrentInstance().getExternalContext().getRe
questMap().get("bindings");
FirstCareAppModuleImpl fc =
(FirstCareAppModuleImpl)bc.findDataControl("FirstCareAppModuleDataControl").getD
ataProvider();
ViewObject vo_SitSocProf = fc.findViewObject("EpisodiosMain");
vo_SitSocProf.executeQuery();
System.out.println(" All done. Ciao ");
return "back";
I just want to refresh data from database and still show the current record. This is always taking me to the first record in the iterator.
The issue is: How to show the current record after the refresh? If the above
code is not correct, or not the most adequate, please don't hesitate and tell
me.
Thanks.

You can do this as follow:
1) In your ApplicationModule (e.g ScottAM) define function:
public void refreshView(){
getMainViewObject().executeQuery();
2) Expose this function to client
3) In your manage bean define:
public String commandButton_save_action() {
String dc = "#{data.ScottAMDataControl.dataProvider}";
FacesContext ctx = FacesContext.getCurrentInstance();
ValueBinding vb = ctx.getApplication().createValueBinding(dc);
ScottAM am = (ScottAM)vb.getValue(ctx);
am.refreshView()
return null;
Note, that this solution will set you on the first row after invoke.
