Hi. Since the update to 12168 I am getting an MNU... Tracked down to showMenuOf: selectorCollection withFirstItem: firstItem ifChosenDo: choiceBlock withCaption: aCaption "Show a sorted menu of the given selectors, preceded by firstItem, and all abbreviated to 40 characters. Use aCaption as the menu title, if it is not nil. Evaluate choiceBlock if a message is chosen." | index menuLabels sortedList | sortedList := selectorCollection asSortedCollection. menuLabels := Array streamContents: [:strm | strm nextPutAll: (firstItem contractTo: 40). sortedList do: [:sel | strm nextPutAll: (sel contractTo: 40)]]. index := UIManager default chooseFrom: (menuLabels substrings) lines: #(1). index = 1 ifTrue: [choiceBlock value: firstItem]. index > 1 ifTrue: [choiceBlock value: (sortedList at: index - 1)] The following revision seems to work ok... showMenuOf: selectorCollection withFirstItem: firstItem ifChosenDo: choiceBlock withCaption: aCaption "Show a sorted menu of the given selectors, preceded by firstItem, and all abbreviated to 40 characters. Use aCaption as the menu title, if it is not nil.
