What steps will reproduce the problem? 1. Import pyactivemq 2. 3.

What is the expected output? What do you see instead?

When built with Visual Studio 8, the output is:

RuntimeError: extension class wrapper for base class class cms::Destination has not been created yet

According to this thread:

http://mail.python.org/pipermail/c++-sig/2004-March/006991.html

defining BOOST_PYTHON_TYPE_ID_NAME might be the way to fix this problem. But when I do this with Visual Studio 8, there's a crash when importing the module.

Will investigate further.

A boost::python::error_already_set was being thrown inside the class_ stuff for Topic, which derives from Destination. I moved the class_ for Destination to precede its derived classes and the problem went away.
