[JBoss JIRA] Created: (JBPM-2677) Migration of process instances fails when there are no process instances

by Edgar Vonk (JIRA)

Migration of process instances fails when there are no process instances ------------------------------------------------------------------------ Key: JBPM-2677 URL: https://jira.jboss.org/jira/browse/JBPM-2677 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Reporter: Edgar Vonk When the process definition includes a 'migrate-instances' entry like: {code} <migrate-instances versions="*"/> {code} The migration of process instances fails when there are no process instances in the jBPM database: {quote} EXCEPTION ########################################### 16:15:36,793 INF | [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.DeployCmd@1a550 f9 java.lang.IndexOutOfBoundsException: fromIndex = -1 at java.util.SubList.<init>(AbstractList.java:600) at java.util.RandomAccessSubList.<init>(AbstractList.java:758) at java.util.AbstractList.subList(AbstractList.java:468) at org.jbpm.pvm.internal.migration.InstanceMigrator.getProcessesToMigrate(InstanceMigrator.java:104) at org.jbpm.pvm.internal.migration.InstanceMigrator.getProcessInstancesToMigrate(InstanceMigrator.java:84) [..] {quote} This issue is caused by the following code in the InstanceMigrator class: {code} private static List<ProcessDefinition> getProcessesToMigrate(String processDefinitionName, MigrationDescriptor migrationDescriptor) { RepositorySession repositorySession = EnvironmentImpl.getFromCurrent(RepositorySession.class); List<ProcessDefinition> processDefinitions = repositorySession .createProcessDefinitionQuery() .processDefinitionName(processDefinitionName) .orderAsc(ProcessDefinitionQuery.PROPERTY_VERSION) .list(); int startIndex = calculateStartIndex(processDefinitions.size() - 1, migrationDescriptor); int endIndex = calculateEndIndex(processDefinitions.size() - 1, migrationDescriptor); if (startIndex > endIndex) startIndex = endIndex; return processDefinitions.subList(startIndex, endIndex); } {code} No check is done to see if the list of processes (processDefinitions) is not empty. This issue causes our unit tests to fail since our unit tests start with an empty jBPM database. -- 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

[JBoss JIRA] Created: (JBPM-2537) A triggered timer does not end the task which is left

by Alexis Seigneurin (JIRA)

A triggered timer does not end the task which is left ----------------------------------------------------- Key: JBPM-2537 URL: https://jira.jboss.org/jira/browse/JBPM-2537 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0, jBPM 4.1 Reporter: Alexis Seigneurin In my process definition, "task1" has a transition with a due date. When this timer is triggered by the job executor, the transition takes the process to "task2" but "task1" still looks active. For instance, when I run a "task query", instead of only finding "task2", both "task1" and "task2" are found. Here is my process definition: <?xml version="1.0" encoding="UTF-8"?> <process name="test1" xmlns="http://jbpm.org/4.0/jpdl"> <start g="-9,192,48,48" name="start1"> <transition g="-44,-18" name="to task3" to="task3" /> </start> <end g="490,192,48,48" name="end1" /> <task g="272,189,92,52" name="task1"> <transition g="-42,-18" name="to end1" to="end1" /> <transition g="-45,-18" name="to java1" to="reminder"> <timer duedate="10 seconds" /> </transition> </task> <java class="fr.idm.SimpleReminder" g="272,316,92,52" method="remind" name="reminder"> <transition to="task2" /> </java> <end g="626,319,48,48" name="end2" /> <task g="454,316,92,52" name="task2"> <transition g="-42,-18" name="to end2" to="end2" /> </task> <task g="113,189,92,52" name="task3"> <transition g="-44,-18" to="task1" name="to end1" /> </task> </process> For testing purpose, I introduced "task3" before "task1". It is not listed by the task query, which makes me think that, once "task1" is left, it should no longer be active. This looks like https://jira.jboss.org/jira/browse/JBPM-967 but the suggested solution does not seem applicable to JBPM 4.x. I will attached the whole source code. -- 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

[JBoss JIRA] Created: (JBPM-2444) sub-process-key does not evaluate EL

by Robert Moskal (JIRA)

sub-process-key does not evaluate EL ------------------------------------ Key: JBPM-2444 URL: https://jira.jboss.org/jira/browse/JBPM-2444 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0 Reporter: Robert Moskal I thought that the sub-process-key (or id) could be an expression the way name could be in the 3.2 product. However, specifying something like this: <sub-process g="228,193,92,52" name="ConcreteWork" sub-process-key="#{SKYLINE_FLOW}"> Always results in the literal value being passed to SubProcessActivity subProcessKey. So, in the above example subProcessKey is "#{SKYLINE_FLOW}" -- 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

[JBoss JIRA] Created: (JBPM-1162) Problem with exception handling within the Decision nodes

by Jon Folland (JIRA)

Problem with exception handling within the Decision nodes --------------------------------------------------------- Key: JBPM-1162 URL: http://jira.jboss.com/jira/browse/JBPM-1162 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: Vaio laptop running Windows Vista, Java 1.5, JBPM 3.2.2 Reporter: Jon Folland Assigned To: Tom Baeyens I believe there may be a bug in the Decision class where exception handling is concerned which causes this failure: If the line: String transitionName = decisionHandler.decide(executionContext); ... ...in the method public void execute(ExecutionContext executionContext) throws an exception, which is caught here in the same method: raiseException(exception, executionContext); We miss the block: if (transition==null) { transition = getDefaultLeavingTransition(); log.debug("decision didn't select transition, taking default "+transition); } So when executionContext.leaveNode(transition); is called at the bottom, there wil be no transition set. I believe we need to check for a tranistion==null condition regardless of whether an excpetion has been handled. Otherwise you will never be able to handle an exception in a Decision without another unhandled exception being thrown (which kind of defeits the point :-) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2641) taskService.addTaskParticipatingUser adds multiple participations for a user

by Robert Moskal (JIRA)

taskService.addTaskParticipatingUser adds multiple participations for a user ---------------------------------------------------------------------------- Key: JBPM-2641 URL: https://jira.jboss.org/jira/browse/JBPM-2641 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Environment: JDK 1.6 HSQL Reporter: Robert Moskal Perhaps this is the intended behavior, but calling taskService.addTaskParticipatingUser with the same user creates multiple participates: taskService.addTaskParticipatingUser(_task.getId(), "boss_rigging", Participation.CANDIDATE); taskService.addTaskParticipatingUser(_task.getId(), "boss_rigging", Participation.CANDIDATE); assertEquals(1,taskService.createTaskQuery().candidate("boss_rigging").activityName("Investigate").list().size()); The query comes back with two tasks.

JBPM 4.3 EL cannot read null process variable - javax.el.PropertyNotFoundException is thrown -------------------------------------------------------------------------------------------- Key: JBPM-2777 URL: https://jira.jboss.org/jira/browse/JBPM-2777 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.3 Environment: tested on windows vista and ubuntu 9.10 Reporter: Jakub Sobolewski Attachments: test.zip EL cannot read process variable set to null value. Variable is seen from Java code. When I try to access it in JPDL by EL expression javax.el.PropertyNotFoundException is thrown. Simple test case (maven eclipse project) in attachment - it contains 1 process definition and 2 tests which show the issue. -- 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

[JBoss JIRA] Created: (JBPM-2750) need delete the duplicated field 'state' in TaskImpl

by Huisheng Xu (JIRA)

need delete the duplicated field 'state' in TaskImpl ---------------------------------------------------- Key: JBPM-2750 URL: https://jira.jboss.org/jira/browse/JBPM-2750 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.3 Environment: Windows XP, JDK1.5.0_15, Maven-2.2.1 Reporter: Huisheng Xu Fix For: jBPM 4.4 How could we find out this bug? If you invoke repositoryService.suspendDeployment(deploymentDbid), you will find out that the state of relative tasks is still 'open'. Because there is a duplicated field 'state' in both TaskImpl and ScopeInstanceImpl. when we invoke 'taskImpl.suspend()' method, this method is defined in ScopeInstanceImpl. in this method, the 'state' of ScopeInstanceImpl field will be changed to 'suspend', but the 'state' of TaskImpl field still be 'open', so in the end, no matter how we invoke the suspend() method, the TaskImpl is still open, it won't be suspended. So I think we should delete the duplicated field 'state' of TaskImpl. -- 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

[JBoss JIRA] Created: (JBPM-2755) EL support in task

by henry donnell (JIRA)

EL support in task ------------------- Key: JBPM-2755 URL: https://jira.jboss.org/jira/browse/JBPM-2755 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: jBPM 4.4 Reporter: henry donnell Fix For: jBPM 4.4 it would be helpful to be able to use EL in the <description> tag of the (human) task node. This will allow to create dynamical task descriptions based on the process variables. Example: <task name="review_task"> <description>Review order nr.#{order.nr} from customer #{order.customer.name}</description> </task> The main purpose is to make human task descriptions in the task list more readable and user-friendly. Because if you have 20 task instances of the same task and they are all called "Review order from customer" it is really hard to see at a first glance which task is related to which customer. -- 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

[JBoss JIRA] Created: (JBPM-2642) A patch to support DB2 on zOS

by Richard L. Burton III (JIRA)

A patch to support DB2 on zOS ----------------------------- Key: JBPM-2642 URL: https://jira.jboss.org/jira/browse/JBPM-2642 Project: jBPM Issue Type: Patch Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.8, jBPM 3.2.7 Environment: Java version: 1.6.0_16,Sun Microsystems Inc., OS-System: Windows XP 5.1,x86, jboss-soa-p.4.3.0, DB2, version: DSN09015, Hibernate 3.2.4.sp1.cp08 Reporter: Richard L. Burton III Priority: Blocker Attachments: findJobsWithOverdueLockTime.patch When using jBPM with DB2 on zOS the JobSession object throws an exception when trying to find jobs with overdue lock time. The exception thrown is: DB2 SQL error: SQLCODE: -180, SQLSTATE: 22007, SQLERRMC: 1 I attached a patch which corrects this problem. Currently JobSession#findJobsWithOverdueLockTime(Date) is using Query#setDate(..) instead of Query#setTimestamp(...) This isn't a problem when using the DB2 Universal version on windows, only on zOS. -- 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
