wicketAjaxGet and wicket 1.5 and StalePage exceptions

[Jason Novotny]

Hi,
    Recently converting an app from wicket 1.4.18 to wicket 1.5.2 and 
am now seeing stack traces like the following:

org.apache.wicket.request.mapper.StalePageException
    at 
org.apache.wicket.request.handler.PageProvider.getStoredPage(PageProvider.java:302)
    at 
org.apache.wicket.request.handler.PageProvider.resolvePageInstance(PageProvider.java:257)
    at 
org.apache.wicket.request.handler.PageProvider.getPageInstance(PageProvider.java:165)

I've tracked it down to a wicketAjaxGet request invoked on the client 
that looks something like this:

var wcall = wicketAjaxGet(url + args, function() { }, function() { });

url looks something like: "'myBuildings?52-1.IBehaviorListener.2-' which 
I create from AbstractDefaultAjaxBehavior.getCallbackUrl().toString()

It seems the problem has to do with page versioning not matching the 
page on the server.

Is there a workaround or another way to code this up? Let me know if I 
can provide any additional information.

    Thanks, Jason
