I can't reproduce this error. It works form e. Take a look into trunk. In the Example, the DraggableElement (draggable1) is now a panel with some draggable element inside. The whole panel gets replaced if you klick on the "AjaxLink". Dragging still works after the replacement.
You can respond to my email address directly. I don't thik we need to flood the list with this special case. And if your native language sould be german...

Having: Panel myPanel = new MyPanel("panelId"); depending how is "rendered" by 1. addOrReplace(myPanel) in a page constructor or by 2. target.addComponent(myPanel) in an event callback method the result is different !
