Actually the reloadData and datasource issues with NSTableView are reported often. Please try to "google" or "bing" these issues and you will be amazed on how many complaints are out there.
Xcode could for example flag the datasource method where I had capitalized objectValueForTableColumn, either by pointing out that the method does not exist in interface or that I need to implement datasource methods correctly. Unfortunately, sometimes one may not share all the code for confidentiality reasons. As you said, one bites the bullet, rewrites the code, and moves on.
