Hi,��I started to play with slots and I am observing odd behaviour after the class structure gets changed.��I am having classes:Object subclass: #CTAslots: { #x. #b => ToManyRelationSlot inverse: #a inClass: #CTB }classVariables: { ��}category: ���ClassTest'and��Object subclass: #CTBslots: { #x. #a => ToOneRelationSlot inverse: #b inClass: #CTA }classVariables: { ��}category: ���ClassTest'then I create instance of CTA and CTB pointing to CTA:a1 := CTA new x: 1; yourself.b1 := CTB new x: 1; a: a1; yourself.the a1 is updated as expected with b having RelationSet with my CTB instance.��The problem is when I decided to update the class CTA - changing position of slot �� #b => ToManyRelationSlot inverse: #a inClass: #CTB.��In the case I drop all the instances of CTA and CTB and recreate new by code above, the inverse update always addresses slot on same position as before ��and not the one with right name.For example when I change it like :Object subclass: #CTAslots: { #x. #children => ToManyRelationSlot inverse: #parent inClass: #CTA.��#b => ToManyRelationSlot inverse: #a inClass: #CTB.��#parent => ToOneRelationSlot inverse: #children inClass: #CTA }classVariables: { ��}category: ���ClassTest'the result of the code��a1 := CTA new x: 1; yourself.b1 := CTB new x: 1; a: a1; yourself.is that slot children gets updated having RelationSet with my CTB instance instead of slot b which has empty RelationSet.The question is: Am I doing something wrong ? Is there any way how to tell class to reinit slots as its order has changed ?Thanks,��Jan��
