Hi,

I'm new to hibernate and got stuck in ArrayOutOfBoundsException while saving object. Please take a look on the error and give me some hints.

Hibernate version: 2.1.3

Mapping documents:
<class name="Client" table="client">
<id name="cid" column="cid" type="java.lang.Integer">
<generator class="sequence">
<param name="sequence">client_cid_seq</param>
</generator>
</id>


Name and version of the database you are using: PostgreSQL 7.4.2-31

Full stack trace of any exception that occurs:
Hibernate: select nextval ('client_cid_seq')
Hibernate: insert into client ('name', 'cid') values (?, ?)
