[Cppcms-users] Set a null value on JSON without quotes

[Daniel R. <dan...@li...>]

Hello there ! I've need to set a null value on JSON without quotes, I've tried the following:
my_object["name"] = NULL; my_object["name"] = "null";
On the first case I've got "my_object": 0  and then "my_object":"null"   
But I've need "my_object":null 
Any clue ?
Daniel
