Netbeans doesn't suggestion methods when I have several files

I have a php project with several files in netbeans. Lets say in one fi开发者_运维百科le looks like this:

<?php
$foo = new Foo();

?>

When I type $foo-> in this file Netbeans suggests all the methods and properties. When I start typing $foo-> in a different file Netbeans suggests that I mean $foo, so fare so good. But then Netbeans has forgotten about the type and doesn't suggest any methods.

Also /* @var $foo Foo */ does not help.

Is it possible to tell netbeans that $foo is always a object of the Class Foo?

I don't believe there's a way to. You should file this as a bug: http://netbeans.org/community/issues.html
