I've updated the JHS grid demo after figuring out how to get data out of the free version of DHTMLX. http://bakerjd99.wordpress.com/2012/12/04/more-about-jhs-with-dhtmlx-the-grid/ The convert/json addon is slow for large arguments. Can anybody suggest alternatives? -- John D. Baker bakerjd99 at gmail.com
