"Joining of non-concurrent decision paths seems to be broken in 4.4" To view the discussion, visit: http://community.jboss.org/message/555138#555138 -------------------------------------------------------------- Hello All, We have a quite complicated process definion with a lot of cases where a step has to be executed only on specific condition - something like the following diagram (see attached full example process definition JPDL file): http://community.jboss.org/servlet/JiveServlet/showImage/4429/ForkJoinTest.png http://community.jboss.org/servlet/JiveServlet/downloadImage/4429/450-189/ForkJoinTest.png We used join nodes with *multiplicity="1"* setting to join the two possible outcome paths of the decision node: *<join g="347,51,48,48" multiplicity="1" name="join1"> <transition g="424,76:-7,-17" name="to join2" to="join2"/> </join>* This approach used to work OK with JBPM 4.3 but it fails with version 4.4. It seems that the handling of join nodes has been changed in this version: the first join node sets state to ended on the incoming execution which is not destroyed at that step but is delegated through to the outgoing transition, so the next join node (the last one before the end in the example) fails with the following exception: Exception in thread "main" org.jbpm.api.JbpmException: execution[ForkJoinTest.10001.to script2.10002] is not active: ended at org.jbpm.pvm.internal.model.ExecutionImpl.checkActive(ExecutionImpl.java:1084) at org.jbpm.pvm.internal.model.ExecutionImpl.take(ExecutionImpl.java:481) at org.jbpm.jpdl.internal.activity.ForkActivity.execute(ForkActivity.java:95) at org.jbpm.jpdl.internal.activity.ForkActivity.execute(ForkActivity.java:46) at org.jbpm.pvm.internal.model.op.ExecuteActivity.perform(ExecuteActivity.java:60) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperationSync(ExecutionImpl.java:672) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperation(ExecutionImpl.java:632) at org.jbpm.pvm.internal.model.ExecutionImpl.start(ExecutionImpl.java:217) at org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd.execute(StartProcessInstanceInLatestCmd.java:63) at org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd.execute(StartProcessInstanceInLatestCmd.java:36) at org.jbpm.pvm.internal.svc.DefaultCommandService.execute(DefaultCommandService.java:42) at org.jbpm.pvm.internal.tx.SpringCommandCallback.doInTransaction(SpringCommandCallback.java:45) at org.springframework.transaction.support.TransactionTemplate.execute(TransactionTemplate.java:130) at org.jbpm.pvm.internal.tx.SpringTransactionInterceptor.execute(SpringTransactionInterceptor.java:49) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.executeInNewEnvironment(EnvironmentInterceptor.java:53) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:40) at org.jbpm.pvm.internal.svc.RetryInterceptor.execute(RetryInterceptor.java:56) at org.jbpm.pvm.internal.svc.ExecutionServiceImpl.startProcessInstanceByKey(ExecutionServiceImpl.java:67) For me, this seems to be a bug - clearly, the behaviour of JBPM has been changed between version 4.3 and 4.4. The attached process definition is executed correctly with JBPM 4.3. What do you think about this?
