[jboss-user] [JBoss jBPM] - problem while deleting processInstance

Hi, I am trying to delete a processIntance using GrapSession object. What I have looks like GraphSession session = context.getGraphSession(); ProcessInstance processInstance = null; if (session != null) { processInstance = session.getProcessInstance(processInstanceId); if (processInstance != null) { session.deleteProcessInstance(processInstance); } } When I do this i get a hibernate exception. org.springframework.dao.DataIntegrityViolationException: Hibernate operation: Could not execute JDBC batch update; SQL [delete from JBPM_MODULEINSTANCE where ID_=?]; Cannot delete or update a parent row: a foreign key constraint fails (`forms/jbpm_swimlaneinstance`, CONSTRAINT `FK_SWIMLANEINST_TM` FOREIGN KEY (`TASKMGMTINSTANCE_`) REFERENCES `jbpm_moduleinstance` (`ID_`)); nested exception is java.sql.BatchUpdateException: Cannot delete or update a parent row: a foreign key constraint fails (`forms/jbpm_swimlaneinstance`, CONSTRAINT `FK_SWIMLANEINST_TM` FOREIGN KEY (`TASKMGMTINSTANCE_`) REFERENCES `jbpm_moduleinstance` (`ID_`)) java.sql.BatchUpdateException: Cannot delete or update a parent row: a foreign key constraint fails (`forms/jbpm_swimlaneinstance`, CONSTRAINT `FK_SWIMLANEINST_TM` FOREIGN KEY (`TASKMGMTINSTANCE_`) REFERENCES `jbpm_moduleinstance` (`ID_`)) am I missing something? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072248#...
