I was unclear, that's what I ment with my last sentence, that we could just update the URL like you did with the filter. Yes, the callback from our ajax request could be used to change the areaName variable, don't think it should be a problem since we getting the new area name from the actual java code, parsed and done from special characters, or? :P Well, it's not a big deal even though I think it would be a little bit nicer, do what you feel for :-)
