Search for ThingLab on the swiki, you will find a changeset that fixes a couple of problems. In particular, the problem that you are seeing can be solved by defining:

UndefinedObject class>>prototype ^ nil

However, there are other problems that arise. Hopefully, I will be able to solve these within the next week.

"I am trying to use the ThingLab but I cannot get past installing it. I downloaded ThingLab v2 today. I am running Squeak 3.2.7 beta 6 (Carbon) updated to 4956 under Mac OS X 10.2.1 on an iMac. I open a new MVC project and file in the Predefs.cs without any trouble at all. As soon as I try to file in the other part, I get the message:

 < You may not create any more undefined objects - use nil. >"

No one offered any ideas. I have confirmed the same problem under Windows 2000. If you know some thing about this software, please let me know if you have any suggestions. MUCH appreciated!
