Redirect to ParentAction Programatically

In your task flow you can redirect parent action programatically using the following method.
   

public void redirectToParentAction(String parentAction) {
        ControllerContext ctrlCtx = ControllerContext.getInstance();
        ViewPortContextImpl portImpl = (ViewPortContextImpl)ctrlCtx.getCurrentViewPort();
        ParentActionEvent parentEvent = new ParentActionEvent(parentAction, true);
        portImpl.queueParentActionEvent(parentEvent);
    }

Thanks
