Strange. I obtain a visualization that looks like this one:

I have no error, except a warning saying that I should use atTypeScope instead of atClassScope.

By the way, I am not sure why we have changed atClassScope -> atTypeScope. Their names implies a different meaning.

Hi

I was following an exercise written by alex and the following code does not work



| superclassEdges |
luModel :=  (MooseModel allInstances last).
luClasses := luModel allModelClasses.
view shape rectangle size: [ :cls | cls queryAllOutgoingInvocations size ].
view nodes: luClasses.
superclassEdges := view edgesFrom: #superclass.
view treeLayout userDefinedEdges: superclassEdges.

view shape line color: Color red.
view edges: luClasses from: #yourself toAll:
[ :cls | cls queryAllOutgoingInvocations atClassScope ]


edgesFrom: raises an error several candidates.

and I do not understand why.
