Fork activities create the wrong type of child executions --------------------------------------------------------- Key: JBPM-2296 URL: https://jira.jboss.org/jira/browse/JBPM-2296 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0.0.Beta2 Reporter: Alexis Seigneurin Attachments: sbox-creation.jpdl.xml With fork activities, child executions are created by calling executionImpl.createExecution (ForkActivity, line 56). In the end, ExecutionImpl.newChildExecution() creates an instance of ExecutionImpl. The issue is that this method should be redefined in the JpdlExecution class. You get this error: Exception in thread "main" org.jbpm.api.JbpmException: unsuppported extension org.jbpm.jpdl.internal.model.JpdlExecution at org.jbpm.pvm.internal.model.ExecutionImpl.getExtension(ExecutionImpl.java:1021) at org.jbpm.jpdl.internal.activity.TaskActivity.execute(TaskActivity.java:48) at org.jbpm.pvm.internal.model.op.ExecuteActivity.perform(ExecuteActivity.java:57) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperationSync(ExecutionImpl.java:589) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperation(ExecutionImpl.java:562) at org.jbpm.pvm.internal.model.ExecutionImpl.take(ExecutionImpl.java:444) at org.jbpm.pvm.internal.model.ExecutionImpl.take(ExecutionImpl.java:448) at org.jbpm.jpdl.internal.activity.ForkActivity.execute(ForkActivity.java:61) at org.jbpm.pvm.internal.model.op.ExecuteActivity.perform(ExecuteActivity.java:57) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperationSync(ExecutionImpl.java:589) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperation(ExecutionImpl.java:562) at org.jbpm.pvm.internal.model.ExecutionImpl.start(ExecutionImpl.java:201) at org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd.execute(StartProcessInstanceInLatestCmd.java:63) at org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd.execute(StartProcessInstanceInLatestCmd.java:39) at org.jbpm.pvm.internal.svc.DefaultCommandService.execute(DefaultCommandService.java:42) at org.jbpm.pvm.internal.tx.StandardTransactionInterceptor.execute(StandardTransactionInterceptor.java:54) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:54) at org.jbpm.pvm.internal.svc.RetryInterceptor.execute(RetryInterceptor.java:55) at org.jbpm.pvm.internal.svc.ExecutionServiceImpl.startProcessInstanceByKey(ExecutionServiceImpl.java:72) To fix it, in JpdlExecution, add this: protected JpdlExecution newChildExecution() { return new JpdlExecution(); } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
