[Pharo-users] Does RoelTyper works?

Hi, I play with RoelTyper, but it does not work as I expect. I have a simple class: -=-=-=- Object subclass: #AMock instanceVariableNames: 'color' classVariableNames: '' poolDictionaries: '' category: 'JK-Mocks’ -=-=-=- with method: -=-=-=- initialize super initialize. color := Color black. -=-=-=- When the following command is evaluated: (TypeCollector typeInstvar: #color ofClass: AMock) types RoelTyper returns "an OrderedCollection(Object)” I expected Color. Do I miss something? Thanks, Juraj
