Hi I got a bug with menu (I'm trying to reproduce it but this is a real bug) because in interpretRegistration: aRegistration item enabled ifNil: [ node enabled: boolean not ] ifNotNil: [:boolean | node enabled: boolean ]. I will not comment on the fact that enabled should return a boolean but the problem is that node does not understand enabled: item enabled ifNil: [ node enabledBlock: item enabledBlock ] node is a MenuRegistration and items is PragmaMenuAndShortcutRegistrationItem ifNotNil: [:boolean | node enabled: boolean ]. And not of course does not understand enabledBlock: interpretRegistration: aRegistration | root | root := MenuRegistration owner: self. aRegistration items do: [:item || node | node := item group ifNil: [ root item: item item ] ifNotNil: [:grp | root group: grp ]. item with ifNotNil: [:block || old | old := aRegistration currentRoot. aRegistration currentRoot: node name. [ node with: block ] ensure: [ aRegistration currentRoot: old ]] ifNil: [ item action ifNil: [ node target: item target; arguments: item arguments; selector: item selector ] ifNotNil:[ node action: item action ]]. node keyText: item keyText; help: item help; icon: item icon; order: item order; parent: item parent. item enabled ifNil: [ node ] ifNotNil: [:boolean | node enabled: boolean ]. item label ifNotNil: [ node label: item label ]. item default ifNotNil: [ :d | node label: node label, ' (', d asString, ')']. item isWithSeparatorAfter ifTrue: [ node withSeparatorAfter ]]
