Comment 3 for bug 98311

Uploaded: room.zip

I put together some minimal files so everyone can see what happens. Install the files in a instance and start Zope 3.

In ZMI choose Room Folder and give it a name. for example "rooms".
Then go to this container. Then you can only add objects from type "Room". For example you add the room "kitchen". If you look at this object you will get informations from the Object Introspector.

Now select the room "kitchen" in the container view and click the copy button. Then click the paste button. Afterwards the container view contains the kitchen object but also the object "Copykitchen".

If you click Copykitchen the Object Introspector shows the roomname as Copykitchen which is correct. But if you look at the roomname of kitchen then the roomname has changed to Copykitchen which is wrong.
