"Re: jBPM 4.2 to 4.4 - Upgrade Issue" To view the discussion, visit: http://community.jboss.org/message/577262#577262 -------------------------------------------------------------- the DBID_ should be unique so the constraint violation is indeed a problem, the engine should generate the DBID_ the config part in jbpm4.cfg.xml looks like this: [...] <object class="org.jbpm.pvm.internal.id.DatabaseDbidGenerator"> <field name="targetExceptionClass"><class class-name="org.hibernate.StaleStateException" /></field> <field name="commandService"><ref object="newTxRequiredCommandService" /></field> </object> <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer" init="eager" /> [...] and I think you are right the problem could be the DbidGenerator generating the same Dbid twice, as far as i remember i have seen in the source somewhere that it is supposed to find the highest Dbid at bootup time, but not sure about that.... -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/577262#577262] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
