Re: gmap2 and permissions
Hi Martin, adding the header contributions in the way suggested works fine for me, and I think this is an acceptable workaround for now. Many thanks for your quick response!

Hi Jan, the good news is that I think we got a better understanding on this question, the bad news is we only can offer a workaround, not an elegant solution. The problem is that Firefox and obviously Konqueror too object to load external

Great, thanks!

Re: gmap2 and permissions
Hi Jan, not sure if Sven or I can come up with something tonight, but it won't be forgotten. http://wicketstuff.org/jira/browse/WSGMAPP-3 Martin Jan Stette schrieb: Some more information after looking further into this - it looks like I'm seeing the same problem as mentioned in this thread: http://www.nabble.com/Google-Maps-and-AJAX-tf4591408.html It only occurs when a Google Map is added via an AJAX request to a page that previously had no Google maps on it. It's easy to reproduce the same problem in the "Many" example in wicket-contrib-gmap2-examples, by commenting out the call to addPanel() at the end of the ManyPage constructor, line 42 in ManyPage.java. Normally this example starts with a single Google map on the page and adds more when the user clicks an AjaxFallbackLink. When this line is commented out, the page starts up with no maps on it, and will fail to add more when the user clicks the link. In Firefox, the error is an "uncaught exception: Permission denied to call method XMLHttpRequest.open", but this is only visible when I have the Firebug debugger enabled. The Ajax link stops working after this error happens. In Konqueror, it shows up as a JavaScript error with code 304, and renders the rest of the page, but the maps aren't drawn, presumably because the XmlHttpRequests are blocked here as well. Subsequent Ajax requests work OK here though. Is this a bug in the gmap2 component that could be addressed?

Re: gmap2 and permissions
Some more information after looking further into this - it looks like I'm seeing the same problem as mentioned in this thread: http://www.nabble.com/Google-Maps-and-AJAX-tf4591408.html It only occurs when a Google Map is added via an AJAX request to a page that previously had no Google maps on it. It's easy to reproduce the same problem in the "Many" example in wicket-contrib-gmap2-examples, by commenting out the call to addPanel() at the end of the ManyPage constructor, line 42 in ManyPage.java.
