I just subclass and redefine rows like this: rows ^ (self context enumeratorFor: self context root) everything contents select: [ :each | (each class = PBPostWithAuthorization) and: [ each notPublished ] ] I would like to put isPostWithAuthorization in PBStructure instead of using class comparisson as there is also isPost but this will requiere a method extension with *-package :( Thanks for the help!
