[GeoNetwork-users] Geonetwork 2.2rc2 + PostgreSQL + GAST + Data Import

Hello,
I'm installing Geonetwork 2.2 rc2 in my server and I want to use Postgresql as database
The problem is that when I use gast to create the tables he starts the process but gets an exception
PSQL Exception:
setObject(i,null) is not supported. Instead use setNull(i, type) or setObject(i, null, type)
someone know what is that?
I also tried to create the tables manually using the sql script for postgresql but when I try to import sample-data it shows up the same exception.
Can someone help me?
