CakePHP Helper Auto-Completion in Netbeans 6.8

Can anyone please tell me how I can "enable" CakePHP's Helper auto-completion in CakePHP? Essentially so when, for instance, I type $form-> it gives me a list of $form's methods and variables.

I have read and also tried to implement comment #3. When I try that it still fails to auto complete in either a Controller or View.

Do any Netbeans & CakePHP users out there have any tips, tricks, or hacks that can get this working? Thanks!
