Tobias Haupt commented on WICKET-4881:
--------------------------------------
I understand it like that: all tasks need to wait but some finish instantly /
synchronously - they don't need the deferred callback to be called at some
future time.
So they don't need further recursion and can continue with the next step in a
simple loop.
I know that there was a quickstart to check the recursion depth and stack size
allready. This should be sufficient. It's hard to simulate the problem.

> I have a problem with Wicket 6.2.0/6.3.0 and IE (this works perfectly with
> Chrome or Firefox). I have a list of items, with Ajax links in the list. The
> response to the Ajax link modifies a panel from the page, and redraws the
> list (its container).
> IE does at least some of the changes correctly, but outputs an error, and it
> seems that subsequent Ajax request fail:
> (... some UI code ...)
> (... Jquery and Wicket ajax references ...)
