Hi Johannes, MethodContext are a bit complicated as you know. However, remembering a bit the code, i THINK the class migration hook may work with it. Have you read: http://rmod.inria.fr/web/software/Fuel/Version1.9/Documentation/Migration Try the materialization with something like: FLMaterializer newDefault migrateClassNamed: #MethodContext toClass: Context.

*Hi there, I'm still migration some stuff to Pharo 4.0 and am aware of the fact that MethodContext was deprecated and Context has to be used instead I'm migrating objects from Pharo 3 using Fuel - that works fine - except if an object is an instantion of a class containing blockclosures any advice ? thanks in advance Johannes *
