Matej Knopp commented on WICKET-534:
------------------------------------

I don't say this would be difficult to add but why on earth would anyone want to do that? Synchronous requests are evil and they lock the browser...

> When using AJAX in certain special cases it may be helpful to make XMLHttpRequest calls with the async parameter set to 'false'. This can be accomplished by modifying the code under wicket-ajax.js -- but it would be nice to have a parameter in the Java code that set the request to synchronous for the length of that call.
