Any ideas why Fuel is looking for OldClass, yet there are no instances

There are no instances, but the class object itself is being held in various places in the Pier kernel.

This can be the problem. Can you update these references to point NewClass?

I want to support in fuel 1.8 some way of specifying that a class has been renamed. Something like:

FLMaterializer newDefault
� � classRenames: { #OldClass -> #NewClass }
� � materializeFrom: aFile.

Would this solve your problem?

cheers,
