Hi. I’m getting this stack trace and I’m wondering if someone can help me debug it. I have this type of binding

NSTableView(value with keyPath name) -> NSArrayController(contentArray with key path ‘shows’, the Object Class is Show) -> NSObjectController.content->MyController

MyController has a “NSMutableArray* shows” attribute and each object in the array is of type Show. Show has a “NSString* name” attribute.

I only get this exception when more than one row exists in the table. Any ideas?
