Check this: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | browser | browser := GLMTabulator withStatusbar. browser column: #one. browser transmit to: #one; andShow: [ :a | a roassal title: 'Numbers in Roassal'; painting: [:view :number | | b | b := [ :startNumber | view shape label. view interaction on: ROMouseClick do: [ :event | ROFocusView new on: event element view: view raw ]. view nodes: (startNumber to: number). view edgesFrom: [:each | each // 5 ]. view treeLayout. view applyLayout ]. "Initial view" b value: 1. view addMenu: 'Refresh' callBack: [ :stack | "We need to clean the view first, else all the nodes get accumulated" view raw elementsDo: #remove. b value: 3 . (browser paneNamed: #one) update ]. ]]. browser openOn: 42 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= I am not sure this is a problem of Glamour. I feel Roassal is missing the abstraction. The main problem is the following: you are using the Mondrian DSL to build your view. However, Mondrian never supported any repaint functionalities. So, trying to do a repaint in Mondrian is not nice. Maybe a new DSL is needed for this. Is the problem fixed? Cheers, Alexandre
