hi,in the chapter that explain the save\open method for the shopping list app i have a problem: i write the implementation like this:

-(BOOL)writeToURL:(NSURL *)absoluteURL oftype:(NSString *)typeName error:(NSError **)outError

{ return[shoppingListArray writeToURL:absoluteURL atomically:YES]; }

-(BOOL)readFromURL:(NSURL *)absoluteURL ofType:(NSString *)typeName error:(NSError **)outError

{ [shoppingListArray release];

shoppingListArray = [[NSMutableArray alloc]
					 initWithContentsOfURL:absoluteURL];

[shoppingListTableView reloadData];

return YES;

}

but when i try to save the file as:”untitled” the system display:

The document “Untitled” could not be saved as “Untitled”.

can anyone help me? thanks
