Re: unregistered_class exceptions are thrown when the derived class are in
an explicitly loaded DLL.
Hello,
In a nutshell, the problem that I have is that an "unregistered_class"
exception is thrown when the derived class is defined/declared in a DLL that
is explicitly loaded.
The problem as far as I can tell is that the derived class in dll and the
derived class in the framework are being "registered" in two different
instances (m_self->m_map.insert(eti); in "extended_type_info.cpp").
Exception is thrown when trying to serialize the foobar_derived_dll. It
looks for "foobar_derived_dll" in the wrong instance of the m_map defined in
the extened_type_info.cpp and then throws an exception.
Can anybody please help

bool m_attr0;
public:

void serialize(Archive & ar, const unsigned int /* file_version */){
std::cout << "serialize foobar_base\n";
ar & BOOST_SERIALIZATION_NVP(m_attr0);
}
