Hi Daria & Norbert, I don't see any i-var called owner in my code. I think you are talking about the empty accessors in SW2WikiObject? These accessors are implemented in SW2InternalLink, since internal links need to know their page to do the lookup of the path. So, in this case the owner is not the parent, but the containing structure. In my opinion, back-links are generally a bad thing and therefor I try to avoid them whenever possible. Have a look at the i-var parent in SW2Structure and SW2Decoration and all the hassle around this. Back-links duplicate information and it makes several things, such as copying, more difficlut. Actually, while traversing a composite with a visitor you have given all the parent nodes implicilty in the context-stack. I don't suggest that you are using the context, but to keep the last node in an i-var or build up a stack of the current path to your visited nodes.
