Using %attribute and %exception together

I am wrapping my get/set methods with an attribute/member for Python as follows:

%attribute(MyObject, double, value, get, set)

Prior to using %attribute I was handling exceptions thrown from the C++ MyObject::set like this:

%exception MyObject::set {

   try {

      $action

   } catch (RangeException &e) {

         PyErr_SetString(PyExc_ValueError, const_cast<char*>(e.what()));

         return NULL;

   }

}

This works fine without %attribute, but no longer works because the set method is called through this macro, thus the code to handle the exception is never inserted:

MyObject_value_set(arg1,arg2);

What is the correct way to use these two constructs together?

Thanks for any hints.
