Hi stefan This is good that you could reproduce it because I was mad at it. I found another case in Moose but esteban could not reproduce it in plain Pharo. We just spent some times chasing the wrong bug :) Stef On 24 Jan 2014, at 14:51, Stephan Eggermont <stephan@stack.nl> wrote:

I would really like a reproducible case… in the form of an image, if no else.

btw… moose 5.0 images are severely broken in that area, so if you are using one of them you *will* have problems.

I can deny that it is a Moose problem, I can reproduce it in Pharo 30716 on mac

Open the image, open a Nautilus browser Add new package AZ Select AST-Core, Nodes Select RBProgramNode Copy the class with right-click menu Rename to AZProgramNode Enter your name (should have happened when creating the new package!) Drag AZProgramNode to AZ Category is not updated.
