Attached is our standalone utility application's source code (we're not running from bpm console). Our test results are   (1) If run the utility with the following steps, it is OK (the sub-process started OK):       %> ....WfeUtility -deploy SubZzA.jpdl.xml       %> ....WfeUtility -all SimSubProc   (2) But if run it with the following steps, it throws exceptions:       %> ....WfeUtility -deploy SubZzA.jpdl.xml       %> ....WfeUtility -start SimSubProc       %> ....WfeUtility -signal SimSubProc.420001 14:59:10,564 SEV | [JDBCExceptionReporter] Cannot add or update a child row: a foreign key constraint fails (`jbpm_4_3/jbpm4_execution`, CONSTRAINT `FK_EXEC_SUBPI` FOREIGN KEY (`SUBPROCINST_`) REFERENCES `jbpm4_execution` (`DBID_`)) ### EXCEPTION ########################################### 14:59:10,564 SEV | [AbstractFlushingEventListener] Could not synchronize database state with session org.hibernate.exception.ConstraintViolationException: could not update: [org.jbpm.pvm.internal.model.ExecutionImpl#420001] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:71) ...... Is it something related to our jBPM's configuration file(s) ? Or something else ? Please remove the package name (at the first line) in my source code when you try it. Thanks a lot in advance.
