Summary: [ruby] Vector template doesn't work

Initial Comment:
When I use a vector template like 

%template(GameObjectVector) std::vector< rl::GameObject* >;

in my code I just geht an exception when loading the DLL:

#<NameError: undefined method `reject!' for class `RlScript::GameObjectVector'>

The generated CXX file looks OK for my (uneducated) eyes. Maybe the exclamation mark doesn't work correctly. I use SWIG trunk from SVN (revision 9855).

Sorry, I missed your comment. My Code still doesn't work with latest
revision from SVN. 

I didn't try your code yet, first I have some information about my
GameObject class. This class is a director class and has a dynamic
downcast.

%apply SWIGTYPE *DYNAMIC { rl::GameObject * };

%feature("director") GameObject;
class GameObject: public ObjectStateChangeEventSource
{
  //...
};

(see
http://svn.berlios.de/svnroot/repos/dsa-hl/rl/trunk/engine/script/swig/RlRules.swig
and
http://svn.berlios.de/svnroot/repos/dsa-hl/rl/trunk/engine/script/swig/RlExports.i)

err.. that -LIBPATH:C:/ruby/lib was to be on the same line ( I hate web
forms ).

Hmm... I'm unable to reproduce your problem.   This works for me with
latest SVN.

Does this work for you?

%module crap

%include std_vector.i

%inline %{

  struct GameObj {
  };

%}


%template(GameObjVector) std::vector< GameObj* >;
