When trying to use two different lazy loaded panels i noticed that they
appear to be serialized. The current implements uses a
AbstractDefaultAjaxBehavior to create the call back to lazy load the actual
content. But these calls appear to be serialized in a page. Would it make
more sense to use a AjaxSelfUpdatingTimerBehavior? Wouldn't that allow for
parallel execution? I'm trying that out now but thought I'd get some
feedback in case there is some fundamental point I'm missing about the
current implementation.
