[Pharo-project] In Latest OB I cannot add a class variable

Hi Lukas. I am using latest OB + RB in PharoDev 1.1 and I have a problem trying to add a class variable. To reprpoduce 1) take any class, for example TestCase. 2) Go to the class side 3) add a class side variable. For example: TestCase class instanceVariableNames: 'history something' 4) The problem is in InteractiveAddClassChange >> definingSuperclass ^ Smalltalk globals at: self superclassName since self superclassName answers nil, because AddClassChange class >> superclassName className isNil ifTrue: [ self fillOutDefinition ]. ^ superclassName className prints -> #'Unknown Class' I attach PharoDebug.log also. Cheers Mariano
