Dynamic JavaServer Faces components

[hev]

Hi,
I have problems with a dynamically created form using this code:

  
  private HtmlPanelGrid grid; 

  public HtmlPanelGrid getDynamicPanelGrid() {
    if (grid == null) {
      Application app = FacesContext.getCurrentInstance().getApplication();
      grid = (HtmlPanelGrid) app.createComponent(HtmlPanelGrid.COMPONENT_TYPE);

      HtmlOutputText text = (HtmlOutputText) app.createComponent(HtmlOutputText.COMPONENT_TYPE);
      text.setValue("some text");
      grid.getChildren().add(text);
    }

    return grid;
  }

I take it from http://wiki.apache.org/myfaces/Programmatic

If I create dynamically an object HtmlInputText (a text field) in this way, I can't get the value of it, modified by the user.
I tried with getValue(), getLocalValue() and I can't :(

Can you help me please?
