dhtmx grid smart rendering issue

I am using dhtmlx grid latest professional version. I am using server side smart rendering and I got this error on console :

Uncaught TypeError: Cannot read property ‘_locator’ of undefined

I had also added total_count and pos attributes in rows element in my xml. Also I use this line for row height :
mygrid.setAwaitedRowHeight(25);
But nothing works for me. Any help will be precious for me. Thank you in advance.

Please, provide with any kind of sample of your code with the init of your grid.

I had find the issue. It is due to the header filters as select filter is not working in case of smart rendering.

Thank you,

Regards,
