Hi, In the following method: MASelectionColumn >> renderCellLinkContent:on: I was wondering if this: html anchor class: (selected isNil ifFalse: [ 'selected' ]); Shouldn't be rather like this: html anchor class: (selected ifTrue: [ 'selected' ]); Note: "selected " is computed as follows:  selected := self isSelected: anObject. Which in principal returns a boolean. Regards, Reza _______________________________________________ Magritte, Pier and Related Tools ... https://www.iam.unibe.ch/mailman/listinfo/smallwiki
