Java Development Tools

hi all ,

i am using j developer 11.1.2.3.39 gR2

and working on creating dynamic menu from database table ,

1. for this i have  two tables in database one fro Modules and other is for SubModule 
2. the Module table is main table as master and the submodule is child , i have create viwlink between these two tables and impliment my logic
3. i have successfully able to create the main menu by following these tutorial  "http://biemond.blogspot.com/2008/11/dynamic-menu-based-on-roles-database.html"
4. but when i try to add the menu item (subModule) in corresponding menu (module)  then this not working ,

the problem is 

how can i get the child rows of a child view by using parent view through bean

here is the modified bean according to my requirement .

where i am wrong ??

public class MenuBean implements Serializable {
    private RichMenuBar initmenu;
    public void createMenu(PhaseEvent phaseEvent) {
        
        // check the menu is already added  
        AppModuleImpl menuAM = getAm();  
        System.out.println("in cretae menu metode");
                boolean addMenu = true;  
                for (Iterator iterator = initmenu.getChildren().iterator(); iterator.hasNext();) {  
                    UIComponent component = (UIComponent) iterator.next();  
                    if ( component.getId().startsWith("menuId")){  
                        addMenu = false;  
                    }  
                }   
                if (addMenu) { 
                    MyMenuImpl menuView =  (MyMenuImpl)menuAM.getMyMenu1();  
                    SubMyImpl  Sub = menuAM.getSubMy1();
                    menuView.executeQuery();  
                    while (menuView.hasNext()) {  
                        MyMenuRowImpl menuItem =  (MyMenuRowImpl)menuView.next();  
                        System.out.println("in finding child");
                       
                      
                        Boolean menuFound = false;  
                        RichMenu menu = new RichMenu();  
                        String menuId = "menuId" + menuItem.getModId().toString();  
          
                        // check if the main menu is already added  
                        for (Iterator iterator = initmenu.getChildren().iterator(); iterator.hasNext(); ) {  
                            UIComponent component = (UIComponent)iterator.next();  
                            if (component.getId().equalsIgnoreCase(menuId)) {  
                                menuFound = true;  
                                menu = (RichMenu)component;  
                            }  
                        }  
                        if (!menuFound) {  
                            // new main menu  
                            RichMenu newMenu = new RichMenu();  
                            newMenu.setId(menuId);  
                            newMenu.setText(menuItem.getMenuName());  
                            System.out.println("the menu " + menuItem.getMenuName() );
                            //newMenu.setIcon(menuItem.getMenuIcon());  
                            initmenu.getChildren().add(newMenu);  
                            menu = newMenu;  
                        }  
                        //---------------------------------------------------------------------------------------
                        RowIterator submod = menuItem.getSubMy1();
                       
                        while (submod.hasNext()){
                            SubMyRowImpl subMenu = (SubMyRowImpl)menuItem.getSubMy1();
                            Row subRow = submod.next();
                            String subName = (String)subRow.getAttribute("Sub");
                            
                            
                        Boolean menuItemFound = false;  
                        String menuItemId = subName;
                        // check if the menu item is already added  
          
                        for (Iterator iterator = menu.getChildren().iterator();  
                             iterator.hasNext(); ) {  
                            UIComponent component = (UIComponent)iterator.next();  
                            if (component.getId().equalsIgnoreCase(menuItemId)) {  
                                menuItemFound = true;  
                            }  
                        }  
                        if (!menuItemFound) {  
                            RichCommandMenuItem richMenuItem = new RichCommandMenuItem();  
                            richMenuItem.setId(menuItemId);  
                            richMenuItem.setText(subName);  
                            System.out.println("the sub value name" + subName);
                           // richMenuItem.setActionExpression(getMethodExpression(menuItem.getAction()));  
                            //richMenuItem.setIcon(menuItem.getIcon());  
                            menu.getChildren().add(richMenuItem);   
                        }
                        } 
                      
                       
                    }  
                    menuView.remove();  
                }  
       
       
    
    }
    
   
               } 
}
