[Cppcms-users] Howto use JSON

Hi,

another question: How can I use the json methods for my own purpose?
I've created a struct with some std::string members and tried

cppcms::json::value value;

value.set("",mystruct);

The compiler claimed that there was an "incomplete type used in nested
name specifier" cppcms::json::traits<mystruct_t>.

Should my struct subclass another class or what else have I done wrong?
How is the JSON encoder to be used?

Thanks for your replies,
Julian

Read documentation of json::value 

http://art-blog.no-ip.info/cppcms_ref_v0_99_1/classcppcms_1_1json_1_1value.html

In order to understand how to save and load data to and from json objects.

And take a look on this discussion.

http://permalink.gmane.org/gmane.comp.lib.cppcms.user/72

For "native" conversion between C++ objects and json objects.

If you will have more questions feel free to ask.

Artyom

Ok, with a few typo corrections the code example worked for me.

Thanks!
