Wait, do you use json here, after the new Ajax.Request? You can't do that. You should put the code using json inside the onSuccess handler. Alternatively, you can add asynchronous: false, to the list of parameters to make the call synchronous, which means that the new Ajax.Request line will block until the response arrives. But this is bad for several reasons: in most of the current browsers it blocks the entire browser until the response arrives, so if the server is slow to respond, you'll lock the user outside the browser; the method might fail, so onSuccess will not be called, and json will still have the wrong value. > This Javascript is in a .js file along with other resources on the server > filesystem.

I can't see how it's different than other ajax calls in xwiki ... > -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
