Keeping session using custom save button in managed bean

Question

Greetings,
I'm building a application based on BC + ADF(JSF).
All around the app. I need two buttons, one for committing and actualizing the UI data, and other to return to the previous page.
Instead of customizing those buttons every time they occurs, I've haded a managed bean to do the work. This managed bean as "request" scope.
The process of editing a form, requires me to have one form to only view the data and other to edit the data.
The issue is: when saving a form, it should return ("back" action) to his precedence, keeping the session state.
That is: If I'm editing "process 2" when i commit it should go to "process 2" in read only mode.
This works fine if i use "hardcoded buttons", but when i use the managed bean to handle those buttons action, when committing, it goes to the first on the list. It doesen't keep the session state.
How can i keep the state ?
Thanks
here it is the managed bean:
package fc.view.backing;
import fc.model.FirstCareAppModuleImpl;
import javax.faces.context.FacesContext;
import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.view.faces.component.core.nav.CoreCommandButton;
import oracle.binding.BindingContainer;
import oracle.binding.OperationBinding;
import oracle.jbo.ViewObject;
public class fcLib {
private BindingContainer bindings;
private CoreCommandButton commandButton_save;
private CoreCommandButton commandButton_backOnePage;
private CoreCommandButton commandButton_backHome;
* Get and set bindings
public BindingContainer getBindings() {
return this.bindings;
public void setBindings(BindingContainer bindings) {
this.bindings = bindings;
* Getters ans setters for "save" and "back" buttons
public void setCommandButton_save(CoreCommandButton commandButton_save) {
this.commandButton_save = commandButton_save;
public CoreCommandButton getCommandButton_save() {
return commandButton_save;
public void setCommandButton_backOnePage(CoreCommandButton btn) {
this.commandButton_backOnePage = btn;
public CoreCommandButton getCommandButton_backOnePage() {
return commandButton_backOnePage;
public void setCommandButton_backHome(CoreCommandButton btn) {
this.commandButton_backHome = btn;
public CoreCommandButton getCommandButton_backHome() {
return commandButton_backHome;
* Back actions for back buttons
public String commandButton_backOnePage_action() {
return "back";
public String commandButton_backHome_action() {
return "home";
* Save button action - Used in al pages that do save (commit) data
public String commandButton_save_action() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("Commit");
OperationBinding operationBinding2 = bindings.getOperationBinding("Execute");
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().getRequestMap().get("bindings");
FirstCareAppModuleImpl fc = (FirstCareAppModuleImpl)bc.findDataControl("FirstCareAppModuleDataControl").getDataProvider();
ViewObject vo_SitSocProf = fc.findViewObject("EpisodiosMain");
vo_SitSocProf.executeQuery();
System.out.println(" All done. Ciao ");
return "back";
}

Hi
I re-execute the query only to refresh the AM VO data.
I'm using AM EO to access DB Views, that use IOF triggers to update/insert/delete into the DB.
Using the application, when updating data, changes wont reflect in the UI if I don't refresh the "master" VO, that is "EpisodiosMain". I'm doing a commit and a execute to a "detail" VO.
"If you need to execute the query and set it back to the last row you worked with, get the row key before executing the query so you can set the current row back to this rowkey"
Could you please throw a example on how to do this ?
"Reaching through to the AM to execute the VO isn't best practices. You should grap the associated iterator in teh binding instead and perform the execute operation. Note that usig ADF binding there are only rare situations in which you need to access teh business service directly as you do. "
Again, could you please post an example of how to do this, or introduce me to some documentation.
Thanks
