[Cppcms-users] cppcms::widgets::file is always not set

[CN <cn...@gr...>]

Basing on ./examples/forms/*, I use cppcms::widgets::file as follows:

   cppcms::widgets::text name;
   cppcms::widgets::file uploaded_file;
   cppcms::widgets::submit submit;
   name.non_empty();
   uploaded_file.non_empty();

This is called as usual:

   c.info.load(context());

My problem is that

   c.info.validate()

always returns false. Widget "name" does have been fed with string, but  
"uploaded_file" is always not set:

   std:cout << c.info.uploaded_file.value()->filename() << std::endl;

raises exception "File was not loaded".

Calling method cppcms::widgets::file::load() does not feed anything to  
itself, either:

   c.info.uploaded_file.load(context());

Helps are much welcome!

Best Regards,
