[JBoss JIRA] Created: (JBPM-2818) Leaving node in super-state throws org.jbpm.JbpmException: cannot leave Node without leaving transition

by Toshiya Kobayashi (JIRA)

Leaving node in super-state throws org.jbpm.JbpmException: cannot leave Node without leaving transition ------------------------------------------------------------------------------------------------------- Key: JBPM-2818 URL: https://jira.jboss.org/jira/browse/JBPM-2818 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.8 Reporter: Toshiya Kobayashi Leaving <node> in <super-state> throws org.jbpm.JbpmException: cannot leave Node(node2) without leaving transition when I execute process definition like: ================ <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="id41"> <start-state name="start"> <transition to="super-state1"></transition> </start-state> <super-state name="super-state1"> <transition to="end"></transition> <node name="node1"> <transition to="node2"></transition> </node> <node name="node2"> </node> </super-state> <end-state name="end"> </end-state> </process-definition> ================= Note: <node name="node2"> doesn't have its own transition. but I expect super-state's transition is available then. The process definition works if you test via ProcessDefinition.parseXmlResource(String xmlResource) without DB/Hibernate (like org.jbpm.graph.exe.SuperStateActionExecutionTest.testNestedSuperStateLeaveViaSuperStateTransition()). What's the difference? org.jbpm.graph.def.Node: ========= public Transition getDefaultLeavingTransition() { Transition defaultTransition = null; if (leavingTransitions != null) { // Select the first unconditional transition for (Iterator i = leavingTransitions.iterator(); i.hasNext();) { Transition auxTransition = (Transition) i.next(); if (auxTransition.getCondition() == null) { defaultTransition = auxTransition; break; } } } else if (superState != null) { defaultTransition = superState.getDefaultLeavingTransition(); } return defaultTransition; } ========= The logic of getDefaultLeavingTransition() depends on whether leavingTransitions is null or not. But in case that hibernate kicks lazy initialization, leavingTransitions will be a zero sized collection, not null. BTW, I think the concept that super-state's transition can be chosen from nodes inside is better to be documented. -- 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-2810) Add API functions to query process definition details (defined tasks, name of nodes etc)

by Peter Horvath (JIRA)

Add API functions to query process definition details (defined tasks, name of nodes etc) ---------------------------------------------------------------------------------------- Key: JBPM-2810 URL: https://jira.jboss.org/jira/browse/JBPM-2810 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Reporter: Peter Horvath It would be great if there were public API methods which provide access to the process definition - for example to retrieve the name of the tasks defined in a 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/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2792) Data manipulation with HQL / SQL nodes

by Peter Horvath (JIRA)

Data manipulation with HQL / SQL nodes -------------------------------------- Key: JBPM-2792 URL: https://jira.jboss.org/jira/browse/JBPM-2792 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: jBPM 4.x Reporter: Peter Horvath Currently HQL / SQL nodes only allow you to run queries. It would be great if it was possible to run data manipulation operations (INSERT / UPDATE / DELETE) as well. It should be quite easy to implement this by adding a new possible flag to the hql / sql node and calling org.hibernate.Query.executeUpdate() from org.jbpm.jpdl.internal.activity.HqlActivity.perform(OpenExecution) method: if(isUpdate) { // isUpdate: this a new flag that indicates that this is a data manipulation operation // execute update and store the number of entities / rows affected (inserted, updated or deleted) by this operation into the result variable result = q.executeUpdate(); } else { if (isResultUnique) { result = q.uniqueResult(); } else { result = q.list(); } } -- 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-2605) DbPersistenceServiceFactory should not close SessionFactory if it didn't opened it

by Stefano Travelli (JIRA)

DbPersistenceServiceFactory should not close SessionFactory if it didn't opened it ---------------------------------------------------------------------------------- Key: JBPM-2605 URL: https://jira.jboss.org/jira/browse/JBPM-2605 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 3.2.7 Environment: JBoss 4.2.3, Seam 2.1 Reporter: Stefano Travelli I configure JBpm with Seam 2.1 so that the JBpm SessionFactory is the same of the underlying SessionFactory used by the EntityManagerFactory in JPA. In order to do so I include JBpm hibernate.cfg.xml in the persistence-unit. Then I declare the JNDI name in jbpm.cfg.xml: <persistence-unit name="getin"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:/getinDS</jta-data-source> <propertyies>  <property name="hibernate.session_factory_name" value="java:/getinSessionFactory"/> <property name="hibernate.ejb.cfgfile" value="jbpm.hibernate.cfg.xml"/> </properties> </persistence-unit> <jbpm-configuration> <jbpm-context> <service name="persistence"> <factory> <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory"> <field name="isTransactionEnabled"> <false/> </field> <field name="sessionFactoryJndiName"> <string value="java:/getinSessionFactory"/> </field> </bean> </factory> </service> <service name="tx" factory="org.jbpm.tx.TxServiceFactory"/> <service name="message" factory="org.jbpm.msg.db.DbMessageServiceFactory"/> <service name="scheduler" factory="org.jbpm.scheduler.db.DbSchedulerServiceFactory"/> <service name="logging" factory="org.jbpm.logging.db.DbLoggingServiceFactory"/> <service name="authentication" factory="org.jbpm.security.authentication.DefaultAuthenticationServiceFactory"/> </jbpm-context> </jbpm-configuration> It works fine except that during test execution in the Seam enviroment JBpm context is opened and closed several times while the persistence unit stays. However, as a JBpm context closes, DbPersistenceServiceFactory also closes the SessionFactory invalidating the EntityManagerFactory. When DbPersistenceServiceFactory doesn't create the SessionFactory taking it from JNDI, it shouldn't close it as this should be a responsibility of the component who registered it in JNDI in first place. The patch is simple: public void close() { if (sessionFactory != null && sessionFactoryJndiName == null) { log.debug("closing hibernate session factory"); sessionFactory.close(); } } -- 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-2644) Investigate problem with EventListeners and missing tasks for user activities

by Sebastian Schneider (JIRA)

Investigate problem with EventListeners and missing tasks for user activities ----------------------------------------------------------------------------- Key: JBPM-2644 URL: https://jira.jboss.org/jira/browse/JBPM-2644 Project: jBPM Issue Type: Task Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.1, jBPM 4.2 Reporter: Sebastian Schneider When you put an EventListener on the start-event of a user task in your process definition and you use a TaskQuery to retrieve the matching task in the user's task list you don't find the task in the list although the execution is already active. Investigate if this behaviour is intended and if it can be changed. -- 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
