  Hi,

     I have a problem with serializing a derived classes through a 
pointer to a base class. I tried registering with the syntax from the 
documentation:

|ar.template register_type<derived_one>();
|

, which works well in case the derived class has a default constructor 
(just like the example). I just don't know what the syntax is for the 
case where the derived class does not have a default constructor (if I 
use the same syntax to register the derived class then I get a 
compilation error about the fact that there is no. I can provide an 
example in case this is not clear enough.

Or, is it an absolute requirement for all derived classes to have a 
default constructor?

Thank you and best regards,
Dante
