问题
Today i've downloaded Eclipse Kepler and i've noticed that PHP code completion is not working anymore. when i type the first letters of a standard php function then press CTRL+Space, it gives me an empty list ("No Default Proposal"). This used to work with the older version (i was using Juno) and i've made no modification.
I've already tried removing the PHP nature and adding it again (through Right Click => Configure => Add PHP Support), but it didn't help.
In both versions the only plugin i have installed is Aptana Studio 3.5.0 (nightly build) but i'm using Eclipse's editor for PHP, not Aptana's, nor i'm using Aptana's PHP nature, but Eclipse's

Try clearing the PDT index. See http://www.eclipse.org/forums/index.php/mv/msg/489559/1065653/#msg_1065653

One more hint, because the solution mentioned above did not help for me: After additionally installing "Dynamic Languages Toolkit Core Frameworks", content assist works again.
