Re: Folder Contents In NSOutlineView

Oops. one little code change, this line:

File *fileDocument = [[File alloc] initWithParent:folderGroup
withName:[filePath lastPathComponent] withPath:filePath
withContents:[NSString stringWithContentsOfFile:filePath] isGroup:NO
isDocument:YES];

Should be:

File *fileDocument = [[File alloc] initWithParent:rootProject
withName:[filePath lastPathComponent] withPath:filePath
withContents:[NSString stringWithContentsOfFile:filePath] isGroup:NO
isDocument:YES];

With the parent name changing.

Sorry about that :-)
