[Zope-CMF] CMF 1.0 to 1.2b2 Failed to import class error.

[Ignacio Valdes]

Hello all,

I recently upgraded from CMF 1.0 to 1.2b2.  A product that I had built 
previously with 1.0 I can no longer look at in the control panel with 
1.2b2 getting the following error when I click on it.  Any suggestions? 
Thanks!
