| Hi, I'm planning to build a core data app for the first time. My data structure is quite complex: a tree of entities (all one-to-many relationships) as follows:
/ C1 B1- D1 / \ E1 / A \ / G \F- H / C2 \ B2- D2 \ E2
1) The Bx entity (and its related Cx,Dx,Ex) is repeated 2 times in the graph (they are the same classes). How can I do it in a neater way? (eg. defining the B->C,D,E subtree, and then instantiating many times...)
2) Is it possible to represent an attribute in common to all entities (e.g. name) in a outlineview+treecontroller using bindings? Any hints?
Thank you very much for your attention. SB
