DHTMLX Grid : Not able to save the grid data

hi there,
I am not able to save the Grid data using serialize() and serializeToCSV() functions.
It gives js error "zx has no properties";
Please help !!!

Please be sure that you correctly specified column types. Such error can occur if you are used incorrect column type name ( grid still able to load data with incorrect settings, but serialization functionality will be broken )

If problem still occurs for you - please provide any kind of sample where problem can be reconstructed.

Please be sure that you have included
    dhtmlxgrid_excell_dhxCalendar.js
in your project, this file is necessary when dhxCalendar column type defined.

When all necessary files included serialization works correctly - please check attached sample.
