[JBoss JIRA] Created: (JBPM-2975) problem with Fork/Join

by doublehero Xu (JIRA)

problem with Fork/Join ---------------------- Key: JBPM-2975 URL: https://jira.jboss.org/browse/JBPM-2975 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Reporter: doublehero Xu Hi,I have get a problem in using the JBPM framework, the version of JBPM framework is 4.2 . You can copy my junit test files into your project and run the AsyncForkTest class as a junit test application, the test result won't be passed.So what just happen? ps.I have another question,Is it a necessary to use a Fork and Join tag at the same time in the xxx.jpdl.xml? Cause in my junit test , I only use the Fork tag. Thanks. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2976) Order of child executions for fork is non-deterministic

by Mike M (JIRA)

Order of child executions for fork is non-deterministic ------------------------------------------------------- Key: JBPM-2976 URL: https://jira.jboss.org/browse/JBPM-2976 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.4 Reporter: Mike M In 4.4, the implementation of the ForkActivity was changed such that a map (Transition -> Child Execution) is now built. Because this is just a generic map without any ordering, the actual order in which the child executions get executed is now non-deterministic. In 4.3, the order was always the same as the order in which the outgoing transitions were listed in the process definition. Now, I'm not sure if this side-effect (making the order non-deterministic) was intentional or not but it definitely break things when other parts of the workflow rely upon a specific ordering. There are definite, real use cases where it is necessary and desirable to specify an explicit order for things. Our workaround was to create a custom activity that is basically exactly the same as ForkActivity, but orders the taking of transitions on child executions so that it is the same as defined in the process definition. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2977) NPE in HistoryActivityInstanceImpl ctor when Activity is null

by Mike M (JIRA)

NPE in HistoryActivityInstanceImpl ctor when Activity is null ------------------------------------------------------------- Key: JBPM-2977 URL: https://jira.jboss.org/browse/JBPM-2977 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.4 Reporter: Mike M In 4.4, automatic history recording was added for custom activities (JBPM-2495). In order to work around (JBPM-2976), we had to create a custom activity that was basically the ForkActivity with slight modification. In the jbpm implementation of the ForkActivity (on which ours was based), it sets the Activity of the root execution to null before launching child executions. When the process engine later executes the history code, the constructor for HistoryActivityInstanceImpl fails with an NPE because the activity is null. Our workaround is to comment out the line in our Fork implementation that sets the Activity to null. Not sure if this has any side effects, but we haven't seen any so far. Now granted, it is a rather odd case to have a custom activity setting the activity to null. But nonetheless, it seems that a generic history mechanism should handle this case gracefully, rather than just throwing an NPE.

[JBoss JIRA] Created: (JBPM-1170) Multiple Timers with same name on Node end prematurely

by David Roberts (JIRA)

Multiple Timers with same name on Node end prematurely ------------------------------------------------------ Key: JBPM-1170 URL: http://jira.jboss.com/jira/browse/JBPM-1170 Project: JBoss jBPM Issue Type: Bug Affects Versions: jBPM jPDL 3.2.2 Environment: Jbpm 3.2.2, Tomcat 5.028, MySQL 5.0 Reporter: David Roberts Assigned To: Tom Baeyens When you have multiple Tasks on a Node, and each task has a Timer called, for example, "Reminder". Lets say each timer is set to repeat every 24 hours. If you complete one of the Tasks on the node, the Timer called "Reminder" on that task instance ends, but so does every other timer for all other tasks on that node with the name "Reminder". Surely this should not happen? You could avoid this by naming each Timer differenty, example "Reminder 1", "Reminder 2". But the problem may still happen if you have multiple task instances of the SAME task. Then the name of the Reminders will still be the same, so they will all end when completing one of the task instances. -- 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-1118) Unexpected behavier of LoggingConfigDbTest

Unexpected behavier of LoggingConfigDbTest ------------------------------------------ Key: JBPM-1118 URL: http://jira.jboss.com/jira/browse/JBPM-1118 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Reporter: Jan-Philipp Bolle Assigned To: Tom Baeyens Priority: Trivial It looks like that the LoggingConfigDbTest is not working. I added in nologging.jbpm.cfg.xml the org.jbpm.logging.db.DbLoggingServiceFactory. Now I assume that the test must fail because jBPM is configured to use the loggingservice. But the test still work (is green). -- 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-2696) Timers should be read after node-enter actions

by Bernd Ruecker (JIRA)

Timers should be read after node-enter actions ---------------------------------------------- Key: JBPM-2696 URL: https://jira.jboss.org/jira/browse/JBPM-2696 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.8 Reporter: Bernd Ruecker Priority: Minor Fix For: jBPM 3.2.x When parsing the processdefinition, timers are read before all events are read. This leads to "create-timer" actions being added to the node-enter events BEFORE your own actions. This doesn't make a lot of sense, normally you want your own actions being executed first and the timer created afterwards. From the runtime perspective, it doesn't make any difference (since the timer is started not before the transaciton commits), but with that behavior you could e.g. calculate due dates on the node-enter event (before the time is created). This is located in the JpdlXmlReader, method "readNode", these two lines: readNodeTimers(nodeElement, node); readEvents(nodeElement, node); See Forum on the discussion how to solve it. -- 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
