by Sofie Ravyts (JIRA)

Description tag on activity not parsed -------------------------------------- Key: JBPM-2785 URL: https://jira.jboss.org/jira/browse/JBPM-2785 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.x Reporter: Sofie Ravyts Fix For: jBPM 4.x When adding descriptions to the activities in the jpdl, these are not parsed: In JpdlParser.java line 308 the description of the process xml element is read instead of the nestedElement (the activity): Element descriptionElement = XmlUtil.element(documentElement, "description"); if (descriptionElement!=null) { String description = XmlUtil.getContentText(descriptionElement); activity.setDescription(description); } -- 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-2794) Constraint vailoation when moving from wait state using timer that result in looping back to the same wait state

by Maciej Swiderski (JIRA)

Constraint vailoation when moving from wait state using timer that result in looping back to the same wait state ---------------------------------------------------------------------------------------------------------------- Key: JBPM-2794 URL: https://jira.jboss.org/jira/browse/JBPM-2794 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.3, jBPM 4.4 Environment: Windows XP, Java 1.6, Test case, JBoss 5.1.0 Reporter: Maciej Swiderski Attachments: jbpm-testcase.zip It is impossible to go from one state where transition is made by timer that goes thru java activity and decision point and gets back to the same state for retry. Problem only exists if timer is assigned to a wait state and all nodes are executed synchnously. Error that is thrown is: 10:57:13,382 WRN | [JDBCExceptionReporter] SQL Error: -104, SQLState: 23000 10:57:13,382 SEV | [JDBCExceptionReporter] Violation of unique constraint $$: duplicate value(s) for column(s) $$: SYS_CT_50 in statement [update JBPM4_EXECUTION set DBVERSION_=?, ACTIVITYNAME_=?, PROCDEFID_=?, HASVARS_=?, NAME_=?, KEY_=?, ID_=?, STATE_=?, SUSPHISTSTATE_=?, PRIORITY_=?, HISACTINST_=?, PARENT_=?, INSTANCE_=?, SUPEREXEC_=?, SUBPROCINST_=? where DBID_=? and DBVERSION_=?] ### EXCEPTION ########################################### 10:57:13,382 SEV | [AbstractFlushingEventListener] Could not synchronize database state with session org.hibernate.exception.ConstraintViolationException: could not update: [org.jbpm.pvm.internal.model.ExecutionImpl#15] Attached is a eclipse project with minimal test case for it that illustrates the problem. The same test project is attached to discussion on forum. Workaround is to make one on the nodes between states to be async. -- 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

[JBoss JIRA] Created: (JBPM-2164) Document JbpmSchema API and ant task

by Taro Yasuma (JIRA)

Document JbpmSchema API and ant task ------------------------------------ Key: JBPM-2164 URL: https://jira.jboss.org/jira/browse/JBPM-2164 Project: JBoss jBPM Issue Type: Task Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.6.SP1 Reporter: Taro Yasuma Document JbpmSchema API and ant task. For instance, to drop jBPM schema you can use the two ways. Programatically: JbpmSchema.dropSchema() Through Ant: <jbpmschema output="${scriptsdir}/jbpm.jpdl.postgresql.sql" config="hibernate.cfg.postgresql.xml" action="drop" delimiter=";"/> We need to elaborate how to use those in our docs. -- 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-1158) Missing query JobSession.findJobsWithOverdueLockTime in hibernate.queries.hbm.xml

by Julien Kronegg (JIRA)

Missing query JobSession.findJobsWithOverdueLockTime in hibernate.queries.hbm.xml --------------------------------------------------------------------------------- Key: JBPM-1158 URL: http://jira.jboss.com/jira/browse/JBPM-1158 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: zip file downloaded from http://www.jboss.org/downloading/?projectId=jbossjbpm&url=http://download... Reporter: Julien Kronegg Assigned To: Tom Baeyens The org.jbpm.db.JobSession class has a findJobsWithOverdueLockTime(Date) method which use a query named "JobSession.findJobsWithOverdueLockTime". In similar methods of the same class, the queries are located in org.jbpm.db.hibernate.queries.hbm.xml, which is not the case for this query. The "JobSession.findJobsWithOverdueLockTime" string could not be found elsewhere in the project. Conclusion: the "JobSession.findJobsWithOverdueLockTime" query seems to be missing in hibernate.queries.hbm.xml (or the method should be removed from the class). -- 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

by Wojciech Gdela (JIRA)

The ClassUtil class is not thread-safe -------------------------------------- Key: JBPM-1139 URL: http://jira.jboss.com/jira/browse/JBPM-1139 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.3 Reporter: Wojciech Gdela Assigned To: Tom Baeyens Attachments: ClassUtil-concurrency-issue.zip The ClassUtil class is not thread-safe. The exception will occur when two thread simultanously try do deserialize variables from two different process definitions. Look at the code: {code} public ContextObjectInputStream(final InputStream in, ProcessInstance processInstance) throws IOException { super(in); this.setProcessInstance(processInstance); ClassUtil.setProcessInstance(processInstance); } ... protected Class resolveClass(final ObjectStreamClass desc) throws IOException, ClassNotFoundException { return ClassUtil.forName(desc.getName(), ContextObjectInputStream.class); } ... ContextObjectInputStream cois = new ContextObjectInputStream(bais, definition.createProcessInstance()); // when here another thread tries to execute the same code with another process instance there will be a problem return cois.readObject(); {/code} Further description of issue is in attached test case. -- 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
