I take that back. [outlineView selectedRow] does appear to tell the absolute truth. So I should now be able to try what you said and tie the tree controller's @"selectionIndexPaths" to [outlineView selectedRow]. I will report back my results... Adam
Ah.. I'm not quite sure you got what I meant. In a (document-based) app set up an NSArray *selectionIndexPaths ivar, so the NSTreeController then binds its @"selectionIndexPaths" binding to the keypath @"File's Owner.selectionIndexPaths" where file's owner (the document) is the owner of the nib containing the tree controller and the outline view. The outline view then has its content bound to the tree controller's @"arrangedObjects" controller key, the selectionIndexPaths to the @"selectionIndexPaths" controller key and then the outline view's table column's @"value" binding is set to the tree controller's @"arrangedObjects.nodeName" (nodeName is just an NSString representation of a file path).
Doing what you said may not work.

Not sure if it will cover all the bases you need though. You'd get an array if selection index paths and then just see if the count of the array is 1 for single selection or more if you have multiple. Jonathan Dann
