The serialization example, test_no_rtti.cpp, appears to only write the base class XML element when saving from the base class pointer. *** why does this appear to be so? Perhaps I am misunderstanding the point of the extended_type_info classes but I thought it was a way to serialize classes with a common base class without having to know the type of the derived class. *** Your understanding of the intent of the test/demo is correct. The example in test_no_rtti.cpp clips the derived portion of the class when serializing from a base class pointer. Please advise. Thanks. *** I'm not seeing this. I just ran it with the debugger and trapped on all the serialize functions of both derived classes.
