Netbeans - ending php code no longer works

Question

Possible Duplicate:
NetBeans PHP Completion

At work, I use netbeans 6.9 on mac os x snow leopard and suddendly php code, the shutdown stopped working. Whenever I use the code completion shortcut, netbeans just tells me “no suggestions”, it would also be clearly possible to complete the function / property. Even in class, when I try to access a method, netbeans does not offer me anything.

I was already looking for a problem, but I did not find any solution. Does anyone else have this problem?

UPDATE:

Flushing the netbeans cache did this as described in this answer: NetBeans PHP Code Completion

This question could probably be closed as a duplicate.
