Problem with shared calendars

Hi,

I installed the zimbra plugin for evolution and everything works like a charm, except the shared calendars. On first time use, I get a login-prompt for every shared calendar. After giving in my credentials the shared calendars are listed under my own zimbra calendar. So far, so good.

Now the problem:
I can't see any appointments from the shared calendars in my evolution.
All calendars have appointments, I can see them in the webinterface, but not in evolution.

I got the plugin from this trunk: SourceForge.net Repository - [zimbraevo] Index of /trunk
