Hi, I do not know exactly what happened, but it looks like simple graphs are not displayed anymore in Mondrian. Try the following and nothing happens: view := MOViewRenderer new. view nodes: #(1 2 3). view open However, this works: view := MOViewRenderer new. view node: 5 forIt: [view nodes: #(1 2 3)]. view open Alex, do you know what the problem is?
