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

[Lukas Renggli]

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
