title: Can I add an element to a RepeatingView without refreshing the latter?
body: <p>Let's say that I have a RepeatingView with complex elements (for example containing applets). I want to add (or delete) a new element to RepeatingView with ajax, but I don't want to refresh all the elements, because it would cause applets to reload, which I obviously don't want.</p>
  
  <p>I am using wicket 1.4.18</p>
  
  <p>Adding to target only the element that I want to add, does not work, I get:
  <code>Component with id (...) was not found while trying to perform markup update. Make sure you called component.setOutputMarkupId(true) on the component whose markup you are trying to update</code></p>
