[Moose-dev] How to refresh a GLMRoassalPresentation

I have to rebuild a visualization create with Roassal. I try this function: ((browser paneNamed: #visu) presentations at:3) update. It send update on the right GLMRoassalPresentation but it never call the painting block used to build my visualization. changeProgramRoot moduleDependencyGraphRoot := self chooseProgramRoot. ((browser paneNamed: #visu) presentations at:3) update. moduleDependencyGraph: composite composite roassal title: 'Program Dependency Graph'; titleIcon: MooseIcons mooseSystemComplexity; painting: [ :view | self renderModuleDependencyGraph: view]; act: [self changeProgramRoot. composite roassal view raw signalUpdate] entitled: 'Program Name'. The act block is called but not the painting block after the update. I look at the Roassal examples but don't find a solution for my problem. What is the way to rebuild a visualization? -- *Guillaume Larcheveque*
