Application hangs up...

[kernel_mode]

Hi all. I am trying to build example from this tutorial: http://www.cocoadev.com/index.pl?ImplementSyntaxHighlighting, but there is a warning:

- (void)awakeFromNib
{
[[textView textStorage] setDelegate:self];  //class 'AppController' does not implement the 'NSTextStorageDelegate' protocol
}

When I try to execute the example it hangs up.

The next question is about IB. Does a TextView have a delegate outlet? It is not listed in outlets section of this component in Interface Biulder.
