If it's very simple, a straight get("path") may be OK, but 
generally it's better to use visitors and/or findParent to 
not depend so much on the exact component hierarchy.

  class StatusMessage extends Label {
  public StatusMessage() {
  super("message", "If you see this message wicket is
  properly configured and running");
  }
  }

 getPage().visitChildren(StatusMessage.class, new
 IVisitor() {
 public Object component(Component component) {
 component.setDefaultModelObject("Deleted");
 }
 });

Timo

Use AdminPage.this.get("message").

2009-01-22 Thread Serkan Camurcuoglu 

using

AdminPage.this.get("message").replaceWith(lbl);

instead of just

this.get("message").replaceWith(lbl);

might work, since message is added to the page, not to the delete button..
