Hi, I'm new with programming for Mac (or any non-web based platform for that matter) so please be gentle as this might be a very dumb question. I have a (document based) core-data application that has two entities that are related through a one-to-may relationship. I want to show data in a single window where the user selects an entry in a table field, and data is displayed related to this entry. I have gotten so far that the data from the selected entity is shown, but now I also want it to show the related data from the other entity. How do I get this to work? I have read through this tutorial: http://themikeswan.wordpress.com/2009/05/22/7/ but the method used here doesn't seem to work for me. Please let me know if you need additional information. Thanks in advance for your help.
