JBPM 4.2 I am unable to complete a task. It throws a hiberanate exception. Any pointers??
I found a JIRA with a similar issue but I am not giving Async as an attribute in the start node but still get the same error https://jira.jboss.org/jira/browse/JBPM-2535?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel JPDL <?xml version="1.0" encoding="UTF-8"?> | | <process key="moves" name="moves" xmlns="http://jbpm.org/4/jpdl";> | <start g="372,12,49,73" name="start1"> | <transition to="Request_New_Move"/> | </start> | <task form="request_move.xsl" g="312,72,169,52" name="Request_New_Move"> | <transition g="-43,-5" name="submit" to="Line_Manager_review"/> | </task> | <task assignee="${reqLoginName}" form="linemanagerreview" g="312,288,169,52" name="Line_Manager_review"> | <notification> | <to users="${task.assignee}"/> | <cc addresses="${lmEmail}"/> | <subject>${task.name}</subject> | <text> | <![CDATA[Hi ${task.assignee}, | Task "${task.name}" has been assigned to you. | ${task.description} | Sent by JBoss jBPM | ]]> | </text> | </notification> | <transition g="-57,-4" name="approve" to="Send_approval_email"/> | <transition g="18,-5" name="reject" to="Send_rejection_email"/> | </task> | <end g="384,480,48,48" name="end1"/> | <mail g="240,408,133,40" name="Send_approval_email"> | <to addresses="[email protected]"/> | <subject>Your move request is approved!</subject> | <text>Employee name ${employeeName} and request details ${requestDetails}</text> | <transition to="end1"/> | </mail> | <mail g="432,408,133,37" name="Send_rejection_email"> | <to addresses="[email protected]"/> | <subject>Your move request is rejected!</subject> | <text>Employee name ${employeeName} and request details ${requestDetails}</text> | <transition to="end1"/> | </mail> | </process> Error org.hibernate.NonUniqueResultException: query did not return a unique result: 2 | at org.hibernate.impl.AbstractQueryImpl.uniqueElement(AbstractQueryImpl.java:844) | at org.hibernate.impl.AbstractQueryImpl.uniqueResult(AbstractQueryImpl.java:835) | at org.jbpm.pvm.internal.hibernate.DbSessionImpl.findTaskByExecution(DbSessionImpl.java:386) | at org.jbpm.jpdl.internal.activity.MailListener.notify(MailListener.java:50) | at org.jbpm.pvm.internal.model.op.ExecuteEventListener.perform(ExecuteEventListener.java:81) | at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperationSync(ExecutionImpl.java:655) | at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperation(ExecutionImpl.java:615) | at org.jbpm.pvm.internal.model.ExecutionImpl.signal(ExecutionImpl.java:416) | at org.jbpm.pvm.internal.model.ExecutionImpl.signal(ExecutionImpl.java:402) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:597) | at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:197) | at org.jbpm.pvm.internal.model.ExecutionImpl_$$_javassist_5.signal(ExecutionImpl_$$_javassist_5.java) | at org.jbpm.pvm.internal.task.TaskImpl.complete(TaskImpl.java:194) | at org.jbpm.pvm.internal.cmd.CompleteTaskCmd.execute(CompleteTaskCmd.java:60) | at org.jbpm.pvm.internal.cmd.CompleteTaskCmd.execute(CompleteTaskCmd.java:32) | at org.jbpm.pvm.internal.cmd.CompositeCmd.execute(CompositeCmd.java:43) | at org.jbpm.pvm.internal.cmd.CompositeCmd.execute(CompositeCmd.java:35) | 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.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:55) | at org.jbpm.pvm.internal.svc.SkipInterceptor.execute(SkipInterceptor.java:43) | at org.jbpm.pvm.internal.svc.TaskServiceImpl.completeTask(TaskServiceImpl.java:105) | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4267694#4267694 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4267694 _______________________________________________ jboss-user mailing list [email protected] https://lists.jboss.org/mailman/listinfo/jboss-user
