I am working on oracle adf with bounded taskflow and generating the ui dynamically on run time but the problem is that the UI components are not clickable and I am unable to click on the ui components, the code is as follows.

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";

}

The UI components showed up properly but they are not clickable any help will be highly appreciated.Thanks

在 ADF/JSF 中动态添加组件是脆弱的。您必须注意 JSF 生命周期和创建新组件的“正确”时间（即，在从先前请求恢复视图状态之后，但在任何新视图状态被序列化之前）。

我已经与 MyFaces 和 Mojarra 团队进行了详细的联系，以确定“正确”的方法（如各方同意）并在此处记录：

这也在我的开源库 Metawidget ( http://metawidget.org ) 中实现，以节省您的辛勤工作:)
