Netbeans don't refresh php code completion

Question

I'm using Netbeans 6.9.1 and php code completion hints don't see the new code I modified, it only refresh at restart.

For example if I add a constant to a class, it don't appear in the code completion, but if I restart nb, then it appears.

Any fix or way to avoid this?

Answer 1

I created again the project and moved the files to the new one. Now seems to work.
