Gantt is missing

Hi,

I can't see the Gantt -chart at all. I tried every possible user profile, but Gantt doesn't appear. Problem is in our server version. As my local version of Projectorria works fine.
Projectorria version 2.1.1 and version 2.2.0 doesn't display any Gantt in server version.
Picture of my data:


Picture of Gantt problem:


In logfile there is error:
2012-05-14 14:39:54 ***** ERROR ***** [1064] SQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1<br/><br/>select * from dependency where successorId in ()

And this is the set up of our server:
OS: Ubuntu 10.04.4 LTS
MySQL: 5.1.61-0ubuntu0.10.04.1
PHP: 5.3.2-1ubuntu4.14

Tested internet browsers are:
Internet Explorer 8
Internet Explorer 9
Firefox 11.0
Firefox 12.0

Thanx,

I have there some activities and milestones, but that doesn't help.

No Java errors.
I change the value of project type to Fixed Price, now the Gantt works ok. If project type is everything else than Administrative, then Gantt works ok. If Project type is Administrative, then Gantt doesn't work. Should it be that way?
