I have a strange crash in 10.5 that doesn't crash in 10.6. My app has a NSTreeController that is bound to an XML document. I am using the "Tree-Based XML Programming Guide for Cocoa: Using Tree Controllers with NSXML Objects" as a guideline.
http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/NSXML_Concepts/Articles/UsingTreeControllers.html Whenever a user drags in files and folders from the Finder the app iterates over the files and inserts them into the tree controller using NSTreeController's insertObject:atArrangedObjectIndexPath: method. If a user drags in a folder, it creates an XML element, inserts it into the tree controller and then iterates over the folder's contents and inserts those as well. This works fine under 10.6, but under 10.5 I am getting the following error logged to the console immediately after there is a file node inserted into the new folder node. The app only displays the folder and one file from that folder. 11/3/09 11:00:08 AM App[225] *** Canceling drag because exception 'NSInternalInconsistencyException' (reason '*** -[NSKeyValueFastMutableArray2 count]: value for key children of object 0x14da3f10 is nil') was raised during a dragging session I am looking for any type of work around for this issue that allows this app to run under both 10.5 and 10.6. Any advice is helpful.
