oracle adf運行時間用戶界面生成

我正在使用有界任務流的oracle adf，並在運行時動態生成ui，但問題在於UI組件不可點擊，我無法點擊ui組件，代碼是如下。oracle adf運行時間用戶界面生成

public String testMethod() { 
    // Add event code here... 

    FacesContext facesContext = FacesContext.getCurrentInstance(); 
    UIViewRoot root = facesContext.getViewRoot(); 


    RichPanelGroupLayout panelGrpLayout = new RichPanelGroupLayout(); 
    panelGrpLayout.setId("pgl1"); 
    panelGrpLayout.setLayout("scroll"); 

    RichMenuBar menuBar = new RichMenuBar(); 
    menuBar.setId("rmb1"); 
    menuBar.setVisible(true); 

    panelGrpLayout.getChildren().add(menuBar); 

    RichCommandButton button = new RichCommandButton(); 

    button.setId("cmi1"); 
    button.setVisible(true); 
    button.setText("First"); 
    button.setPartialSubmit(true); 
    button.setRendered(true); 

    String method = "#{backingBeanScope.CLBean.testMethod}"; 
    Application app = facesContext.getApplication(); 
    ExpressionFactory elFactory = app.getExpressionFactory(); 
    ELContext elContext = facesContext.getELContext(); 
    MethodExpression methExp = elFactory.createMethodExpression(elContext, method, Object.class, new Class[0]); 

    button.addActionListener(new MethodExpressionActionListener(methExp)); 


    root.addComponentResource(facesContext, button); 

    return "product"; 

}

UI組件出現了正常，但他們無法點擊任何幫助將是非常appreciated.Thanks
