  10. >Greg Friedman should be answering this question but I thought that 
  11. >refcounted objects in OpenDoc were created with a refcount of 1? When you 
  12. >create an ODShape (subclass of ODRefcounted object) it's refcount is 1. I 
  13. >am just wondering why your refcount is 0. A refcount of zero means the 
  14. >object is gone.

  16. I'll try to save Greg the trouble.  After re-reading the description of
  17. ODRefCntObject, I think you're right.  The extension creation function should
  18. be setting the refCount to 1, not FW_CExtensionManager::AcquireExtension(). 
  19. A note to that effect might be useful in the Engineering Note on Extensions.
