[lively-kernel] ObjectGraphLinearizer is trying to deserializer instance of lively.Presentation.PageMorph but this class cannot be found

[Robert Krahn]

You can simply link the PartsBin:

workspace=`lk scripts-dir`/workspace
ln -s $workspace/PartsBin $workspace/ww/PartsBin

The next version of livelykernel-scripts will do that automatically.

Best,
Robert
