[omniORB] how to use _dispose() in factory?

[Zsolt Zsoldos]

Hi,

It maybe a silly newbie question, sorry...

I would like to create an object class with a factory for
generating and disposing objects dynamicaly. I defined the
following idl:

module modest
{

  interface BaseObject
  {
      readonly attribute long status;
      oneway void registerSink( in BaseObject sink );
  };

  interface BaseObjectFactory
  {
      BaseObject createObject();
      oneway void destroyObject( in BaseObject me );
  };

};

I am trying to implement the factory operations according to
the signature generated by the stubs:

modest::BaseObject_ptr BaseObjectFactoryImp::createObject()
{
    BaseObjectImp *the_new_obj = new BaseObjectImp();
    the_new_obj->_obj_is_ready( _boa );
    modest::BaseObject_ptr ref_to_new_obj = the_new_obj->_this();
    return ref_to_new_obj;
}

void BaseObjectFactoryImp::destroyObject( modest::BaseObject_ptr  me )
{
    me->_dispose();
    CORBA::release( me );
}

However, I get a compiler error for me->_dispose(), saying that there
is no such member. I see that the _dispose() is defined in the
skeleton class _sk_BaseObjectFactory which inherits from 
BaseObjectFactory. So it looks like, that I should call _dispose()
on my BaseObjectImp object and not on the ancestor BaseObject.
But the signatures as generated require me to use BaseObject_ptr
types. Can I just cast it in the destroyObject() method?
Or should I return a casted the_new_obj pointer from createObject() 
and then cast it back in the destroyObject()? 
Or is there another (clean) way to do this?

Thanks for your help,
Zsolt
