[Moose-dev] Roassal: having changes in shapes

Hola,

for my visualization, I want to be able to change the color of a shape after the view has been opened, depending on a given condition. So I wrote something like below, where the instvar lastview holds the view that was opened.

highlightNode: aName |node| node := lastview elementFromModel: aName. node isNil ifFalse: [ node shape color: (Color red). lastview signalUpdate.]

Sadly, I do not see the shape changing color to red. What can I do to have this working?

Thanks in advance,
