Enabling Global Commit operation in ADF

In order to commit transactions belongs to two data controls with a single commit button in a JSF page.     

First we have to get the DataControlFrame object  which can access all the data controls in the particular application

public void onCommit(ActionEvent actionEvent) {

        // Add event code here...

        BindingContext bc=BindingContext.getCurrent();

        DataControlFrame dcf=bc.findDataControlFrame(bc.getCurrentDataControlFrame());

        Collection<DCDataControl> dccol=dcf.datacontrols();

        for(DCDataControl dCDatacontrol : dccol){

            if(dCDatacontrol.isTransactionDirty()){

                try{

                    dCDatacontrol.commitTransaction();

                }catch(Exception e){

                    FacesContext fc=FacesContext.getCurrentInstance();

                    fc.addMessage(null,new FacesMessage(FacesMessage.SEVERITY_ERROR,e.getMessage(),null));

               e.printStackTrace();

                }

            }

        }

    }
