[Moose-dev] userDefinedEdges

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.
