[Moose-dev] Symbols not define

Hello, I'm beginning with moose and I've a problem with Mondrian I want to generate visualization with this code : view newShape rectangle; height: #numberOfMethods; width: #numberOfAttributes; linearFillColor: #numberOfLinesOfCode within: classes; withBorder. view nodes: classes. view edges: classes from: [:each | each superclass] to: [:each | each]. view treeLayout. I think it's correct because I've found it on http://moose.unibe.ch/tools/mondrian/tour?_s=LrcZtOGEBQIygSJg&_k=RnnrLp… But I've problem with symbols (like #numberOfMethods) : they are not defined. Maybe there is a special manipulation to do ? I've done this : - open Moose - "Open in Mondrian Easel" - inset this code in the window - "generate view" Thanks to help me
