DragAndDropWrapper view refresh

Hi,

I use a DragAndDropWrapper similar to 
https://dev.vaadin.com/svn/demo/sampler/src/com/vaadin/demo/sampler/features/dragndrop/
DragDropHtml5ToFromDesktopExample.java
and want to update my current view instead of opening a new window as shown in the example.
 

StreamVariable streamVariable = new StreamVariable() {
public void streamingFinished(
StreamingEndEvent event) {
// view is updated here
}
};
}

But the view doesn't refresh.
setImmediately() and markAsDirty() didn't help too.

Any Ideas?
