It affects creating a process within          * another just created and not yet persisted process.          */         super.id = new Long(super.dbid).toString();         super.save();     } }   and in jbpm.execution.hbm.xml that is linked to jbpm.hibernate.cfg.xml:   <class name="*RMExecutionImpl*"  table="JBPM4_EXECUTION" discriminator-value="pvm">   The only thing is: had to keep package name org.jbpm.pvm.internal.model   Would still appreciate any other suggestions -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530045#530045
