Thank guys for immediate suppprt ...

 http://community.jboss.org/people/swiderski.maciej Maciej waht kinf of logs of Hibernate I need to activate to help you help me :-)  ?

I'm investigating ... I found that in AcquireDbidBlockCmd property object result from the query obtained from the code reported below is null .

public Long execute(Environment environment) throws Exception {
    Session session = environment.get(Session.class);
    
    PropertyImpl property = (PropertyImpl) session.createQuery(
        "select property " +
        "from "+PropertyImpl.class.getName()+" as property " +
        "where property.key = '"+PropertyImpl.NEXT_DBID_KEY+"'"
    ).uniqueResult();

Here property is null !!

My interested configuration is
....
<task-service />
        <object class="org.jbpm.pvm.internal.id.DatabaseDbidGenerator">
            <field name="commandService">
                <ref object="txRequiredCommandService" />
            </field>
        </object>
        <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer"  init="eager" />

Is it correct ?

How I can debug and understand wich transcations objects are playing and its state ?
