[JBoss JIRA] Created: (JBPM-2944) JBoss Tools jBPM Project Wizard tries to get runtime from a broken link

by David Lambert (JIRA)

JBoss Tools jBPM Project Wizard tries to get runtime from a broken link ----------------------------------------------------------------------- Key: JBPM-2944 URL: https://jira.jboss.org/browse/JBPM-2944 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: GPD Affects Versions: jBPM 4.4 Environment: Rational Software Architect for WebSphere 7.5.3 on Windows XP SP3, IBM JDK 1.6 Reporter: David Lambert Priority: Minor I'm trying to set up a new jBPM project using the JBoss Tools wizard. The second screen asks the user to "Locate a JBoss jBPM Runtime" and offers a link to "Download the JBoss jBPM package if you have none available yet". However, clicking that link opens an Internet Explorer window pointing to http://www.jboss.org/jbpm/downloads/ , which displays the message "Sorry, the page you're looking for cannot be found. Please use the Search box in the header to check that the information isn't located somewhere else." -- 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-2951) TaskService.completeTask fails when called with variables but no outcome

by Jon Kranes (JIRA)

TaskService.completeTask fails when called with variables but no outcome ------------------------------------------------------------------------ Key: JBPM-2951 URL: https://jira.jboss.org/browse/JBPM-2951 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.4 Reporter: Jon Kranes Given a task 'task1' with a single named transition, if I call the variant of completeTask that takes the taskID and a Map of variables, the result is an error: "No unnamed transitions were found for the task 'task1' According to the user guide (Section 5.7), if a task has one outgoing transition with a name, then calling compeleteTask(id, null) is expected to result in an error. It appears that calling completeTask(id, variables) is being treated as equivalent to calling completeTask(id, null, variables) and thus causing an error. This behavior seems incorrect -- completeTask(id, variables) should, aside from setting variables, follow the behavior of completeTask(id), which according to the user guide will complete the task and take the single outgoing transition regardless of whether it is named or not. -- 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-2950) HibernateException is thrown during concurrent Timers persistence

by Borislav Andruschuk (JIRA)

HibernateException is thrown during concurrent Timers persistence ----------------------------------------------------------------- Key: JBPM-2950 URL: https://jira.jboss.org/browse/JBPM-2950 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Reporter: Borislav Andruschuk We deploy ProcessDefinition on application startup and use this one persisted instance during application activity in several threads (i.e. during full application live time). We noticed that during concurrent Timers creation for several processes which build from this ProcessDefinition instance we've got: org.hibernate.HibernateException: identifier of an instance of org.jbpm.graph.def.Action was altered from 532 to 533 After investigation I've noticed that Action instance is persisted anew (not updated) in concurrent threads and new row appears in the table. The problematic place is in org.jbpm.db.JobSession.saveJob where Action is checked on existence in Hibernate Session's persistent context. The suggested fix is to changed condition: !session.contains(action) to action.getId() == 0L This change fixes our problem. -- 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-2949) JBPM4_LOB table its field BLOB_VALUE_ is only 255 bytes using database DB2; SQL ERROR 302

by Bastiaan Asselman (JIRA)

JBPM4_LOB table its field BLOB_VALUE_ is only 255 bytes using database DB2; SQL ERROR 302 ----------------------------------------------------------------------------------------- Key: JBPM-2949 URL: https://jira.jboss.org/browse/JBPM-2949 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.4 Environment: Ubuntu, JBPM 4.4, DB2 9.7, Java 5.0 Reporter: Bastiaan Asselman In my hibernate config I defined to create the table structure. When deploying a jpdl.xml file, the database structure is created. This is done successfully. Unfortunately the length of the BLOB for the column BLOB_VALUE_ of the table JBPM4_LOB is too small, only 255 bytes. My jpdl.xml file is bigger, and can therefor not be stored in the field. This results in the SQL error 302. (the data is too big for the field). If I investigated the jbpm.execution.hbm.xml in the jar jbpm-pvm-4.4.jar, I found that there is no length specified for this field. Strange enough DB2 its default length for a BLOB field is 1MB. -- 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-2956) DispatcherThread integer overflow and make checkForNewJobs volatile

DispatcherThread integer overflow and make checkForNewJobs volatile ------------------------------------------------------------------- Key: JBPM-2956 URL: https://jira.jboss.org/browse/JBPM-2956 Project: jBPM Issue Type: Patch Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.4 Reporter: Michael Wohlfart Priority: Trivial Fix For: jBPM 4.5 I experience an integer overflow in DispatcherThread, also i think checkForNewJobs should be volatile since it might be accessed from different threads, the attached thread should resolve this -- 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-2966) cancel and error end activity throws exception in subprocess

by Philipp Ossler (JIRA)

cancel and error end activity throws exception in subprocess ------------------------------------------------------------ Key: JBPM-2966 URL: https://jira.jboss.org/browse/JBPM-2966 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.4 Environment: jBPM 4.4 Reporter: Philipp Ossler I created a simple process which includes a state and a subprocess with different end activities The subprocess is similar to the example in user guide > http://docs.jboss.com/jbpm/v4/userguide/html_single/#endstate. When I send the signal "end" to the state in the subprocess, the process wait in state "end state". That's correct! But if I send the signal "cancel" or "end", a JbpmException "execution[...] has running subprocess: execution[...] in state cancel/error" throws. This exception throws in method checkActive() of the class ExecutionImpl. {code:java} if (!isActive()) protected void checkActive() { if (!isActive()) { throw new JbpmException(toString() + " is not active: " + state); } else if (this.subProcessInstance != null && !Execution.STATE_ENDED.equals(this.subProcessInstance.getState())) { throw new JbpmException(toString() + " has running subprocess: " + this.subProcessInstance.toString() + " in state " + this.subProcessInstance.getState()); } } {code} The problem is that the methode only check if the subprocess has the state "end". I think the method have to check if the subprocess state is one of {end, cancel, error}.

[JBoss JIRA] Created: (JBPM-2970) DbSessionImpl.deleteProcessDefinitionHistory causes foreign key constrain violation for FK_HACTI_HPROCI
