I am trying to reproduce the Calculator tutorial and everything proceeded smoothly until I wanted to refine the scope for InputFieldReference. As described in the tutorial here the Calculator concept should have a behaviour overriding the Scope definition. When I try to create the overriding method for getScope it does not appear in the list of available methods. If I try to add as suggested jetbrains.mps.scope it is not found (I get j.m.baseLanguage.scopes and j.m.lang.scopes). I have also tried to add in several places j.m.baseLanguage and j.m.smodel in dependencies and used languages but still cannot get the method to be overridden (nor I can get j.m.scope in the list when adding a new language for the behaviour definition).
Did I miss something?
