Description Matthias Wienand CLA 2018-04-20 07:57:39 EDT 
Currently, ZestContentViewer only maintains a content-node-map, i.e. a map from content objects to GEF Graph Node objects. However, given a GEF Graph Node, you have to traverse this map in order to find the corresponding content object.

Instead, ZestContentViewer could store a back reference to the original content object in the created GEF Graph Node.

Comment 2 Matthias Wienand CLA 2019-06-28 08:09:49 EDT 
The back-references are now stored via the attributes of Graph, Node, and Edge objects. They are accessible via ZestProperties as of GEF 5.1.0. Therefore, I resolve this ticket as fixed.
