[nb4.0] How to update code completetions?

Hi,

I have a project in nb4.0 which consists of ~550 classes. Yesterday I have
created 5 more java files in one of my existing packages without using
NetBeans. So when I start NetBeans, I realize that NetBeans did not add
those classes in its code completion database although it checks the class
paths each time I start the IDE. How can I force NetBeans to update the code
completion database for my project? Is there an action like "update code
completions..." like the one in the previous versions?

Thanks in advance,
Yetkin
