Dynamic field drawing using Wicket?

Hello Experts,

I am concentrating to do Wicket sample application. 
I have xml like

<DYNAMIC>
<FIELDS LABELNAME="USERNAME" FIELDTYPE="TEXT"/>
<FIELDS LABELNAME="PASSWORD" FIELDTYPE="TEXT"/>
<FIELDS LABELNAME="COUNTRY" FIELDTYPE="COMBO"/>
</DYNAMIC>

Using the above xml, I want to draw

lable name and texboxes/combo(given above) display.

Is it possible in Wicket?
Kindly send me your suggestion.

Thanks for resposing.

Edward

me to create dynamic fields creation.

Thanks

Taken that you want them to turn up as real components, being able to
receive their own inputs and stuff, you'd need an interpretation.

Roughly

public class MyDynamicPanel extends Panel {

  public MyDynamicPanel(URL xmlDefinition, IModel model) {
    // read and interpret definition
    // create a ListView or Repeater or something similar and
    // for each element you find, you add a panel with the actual
component in it

  }

  protected Panel newTextComponent(String id, ...) { ...

  protected Panel newComboBoxComponent(String id, ... { ...
}

etc.

MyDynamicPanel.html
...
  <ul>
    <li wicket:id="components"> <!-- generated for every component,
e.g. backed by a ListView -->
      <span wicket:id="component">[actual component will be placed here]</span>
    </li>
  </ul>

Then e.g. a text component could be as simple as:

public class TextFieldPanel extends Panel {

  public TextFieldPanel(String id, IModel model) {
    add(new TextField("field", model);
  }
}

TextFieldPanel.html
<wicket:panel>
  <input type="text" wicket:id="field" />
</wicket:panel>

That may seem like more work than needed, but it is very flexible to
work with panels like that.

Hope that helps,

Eelco
