Thanks for an update Martin. Unfortunately using IAjaxCallDecorator#decorateScript() prevents handling request (nothing happens). If I append the stop script directly to ajax request target (before sending event), then request proceeds, but the first lazy component is not loaded.
Also, the stop script breaks ajax indicators (both from lazy components and indicating links). Exceptions still are present, but page isn't crashing. So far the closest solution was using BookmarkablePageLink, but it is not ajax and it is just a workaround. Isn't there a way to prevent Wicket from handling "old" ajax requests? I assume that's how it should work with DROP channel.
