Exporting problem (Unable to export: 'Trying to write out, AnObsoletePRReportView')

I would create an empty class of that name, import the snapshot and
fix references to this class and its instances manually.

Sorry, I misread your mail. I thought you tried to import code that
contained this class into an image that did not contain this class.

In your case your model already contains these obsolete classes. Try
evaluating the following code to fix your model:

PRComponent allInstances do: [ :comp |
       (comp componentClass includesBehavior: PRViewsWidget) ifTrue: [
               comp settings at: PRViewsWidget descriptionViewClasses ifPresent: [ :classes |
                       comp settings
                               at: PRViewsWidget descriptionViewClasses
                               put: (classes reject: [ :each | each isObsolete ]) ] ] ]

After that the export should work fine.

I will add that to the automatic migrations scripts.

Cheers,
Lukas
