Hi James, As a good practice when dealing with JSON in the browser, here is what you can do :
* Check the AJAX response in Firebug. If you don't see a "JSON" tab, then something is wrong (the JSON is not valid). What you can do then is copy the response body from Firebug and submit it on JSONLint (http://jsonlint.com/). It will tell you what's wrong. Hope this helps Jerome 2011/7/21 许凌志(Jamesxu) <[email protected]> > According to Eduard's suggestion, I modify the macro code of > SuggestLuceneService, and it works fine when I visit in browser.
