Warning 303: %extend defined for an undeclared class opencascade::handle.

I get the 303 for following, although the test_ball seems to compile fine?

I just can't figure this out.


%{
#include <Standard_Transient.hxx>

opencascade::handle<int> test_ball;

%}

%extend opencascade::handle
{

};

I've looked into Standard_Transient.hxx and there handle is forward declared as:

namespace opencascade {
  template <class T> class handle;
}

I cannot seem to find the actual class def for handle though.
