Compability between 2.6 and 3.0 version of full dhtmlx

hello ,I am trying to upgrade dhtmlx.js to 3.0 from 2.6. I wont to know how i can do it, becouse when i load a dhtmlxgrid from a url in Json format appears a message: ‘rows.lenght is null or not is a object’ , and the load fails. Thanks.

Make sure that you have added “dhtmlxgrid_json.js” to your code.
