[jboss-user] [jBPM] - Could not delete execution when flow end?

hob wang [https://community.jboss.org/people/hob007] created the discussion "Could not delete execution when flow end?" To view the discussion, visit: https://community.jboss.org/message/723401#723401 -------------------------------------------------------------- I tested a jbpm 4.4 flow connected to MySql integrated with spring and hibernate. The flow deployment and execution were fine, but when the flow end, it was wrong. Cannot delete or update a parent row: a foreign key constraint fails. Test environment: jbpm 4.4 version, mySql 5.0.12, hibernate 3.2, spring 2.5.6 mySql engine: InnoDB hibernate dialect: org.hibernate.dialect.MySQLInnoDBDialect The error stack under this: Hibernate: delete from jbpm4_execution where dbid_=? and dbversion_=? 14:54:57 [http-8080-6] ERROR org.hibernate.util.JDBCExceptionReporter.logExceptions(101) - Cannot delete or update a parent row: a foreign key constraint fails 14:54:57 [http-8080-6] ERROR org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(324) - Could not synchronize database state with session

MySQLInnoDBDialect.  And my MySql DB engine is "InnoDB". I try MySQLInnoDBDialect and MySQLDialect, and the error stack is the same. I wonder is there something wrong with my configuration, how could I do to complete flow test? Sincerely looking for you advice. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/723401#723401] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
