I don't think it is possible, as the URLs are not the same as the real underlying objects.Did you remove the bindings in BibDocument, then? I thought that was still using an array controller.So perhaps to make it possible to bind to the underlying file objects *and* the URLs, we could do something like NSPopUpButton: a "content" binding and a "contentValues" binding. "content" binds to the array of file objects (or more properly, the arrangedObjects of an NSArrayController binding to the array of files), and "contentValues" binds to the same key path with the key for the URL value appended (so to arrangedObjects.fileURL, or perhaps arrangedObjects.displayURL to allow for dummy URLs when the file does not exist). This also allows to build in adding, removing, and moving files.Hmmm...I never bothered to figure out NSPopUpButton's binding. So content is bound to an array proxy, and it uses contentValues to get the rest of the key path? I'm not sure what that would look like in code; would it require adding another array ivar? Bindings are already sort of wedged in on top of the datasource stuff, and I'm definitely hesitant to do something like a complete rewrite at this point and throw out the last 4 months of testing and profiling :). Right now it looks like this: // KVC setter/getter iconURLs changes _iconURLs ivar - (NSURL *)iconURLAtIndex:(NSUInteger)anIndex { NSURL *aURL = [[self iconURLs] objectAtIndex:anIndex]; if (nil == aURL) aURL = [_dataSource fileView:self URLAtIndex:anIndex]; if ([[NSNull null] isEqual:aURL]) aURL = nil; return aURL; } - (NSUInteger)numberOfIcons { return nil == _iconURLs ? [_dataSource numberOfIconsInFileView:self] : [_iconURLs count]; } So internally everything just calls iconURLAtIndex: and numberOfIcons: instead of accessing the _iconURLs ivar or messaging the datasource directly.---------------------------------------------------------------------- ---This SF.net email is sponsored by: Splunk Inc.
