[JBoss JIRA] Created: (JBPM-2588) Attribute for tag decision to validate conditions of transitions

by Wojtas Koziej (JIRA)

Attribute for tag decision to validate conditions of transitions ---------------------------------------------------------------- Key: JBPM-2588 URL: https://jira.jboss.org/jira/browse/JBPM-2588 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Reporter: Wojtas Koziej My proposition is to extend evaluation of condition when selecting leaving transitions <decision condition-evaluation="strict|first-matching|???"> .... </decision> condition-evaluation (or similar attribute) meaning: * strict - all conditions are evaluated, lets name N as number of conditions which evaluates to true. If N != 1 jBPM raise exception. Transitions without conditions are not allowed * first-matching - jBPM evaluates conditions and leave when find first which evaluate to true. If there is no such transition jBPM raise exception. Transitions without conditions are allowed and evaluates to true. * ??? (I don't no how to name it) - this is default and makes that jBPM behaves as described in current documentation : "So first, all transitions with a condition are evaluated. If one of those evaluate to true, that transition is taken. If no transition with a condition resolves to true, the default transition (=the first one) is taken" It will be very helpful during development and testing. -- 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-2589) SuperState - StaleObjectStateException when timer signals the token

by Adrian Apthorp (JIRA)

SuperState - StaleObjectStateException when timer signals the token ------------------------------------------------------------------- Key: JBPM-2589 URL: https://jira.jboss.org/jira/browse/JBPM-2589 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.6.SP1 Environment: Win XP, HSQL, JBOSS 4.2.3 Reporter: Adrian Apthorp When I configure a timer on a superstate a StaleObjectStateException is raised when the timer is fired. org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.graph.exe.Token#578] at org.hibernate.persister.entity.AbstractEntityPersister.check(AbstractEntityPersister.java:1765) at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2407) at org.hibernate.persister.entity.AbstractEntityPersister.updateOrInsert(AbstractEntityPersister.java:2307) at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2607) at org.hibernate.action.EntityUpdateAction.execute(EntityUpdateAction.java:92) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:250) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:234) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:142) at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:298) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) at org.hibernate.transaction.CacheSynchronization.beforeCompletion(CacheSynchronization.java:59) at com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple.beforeCompletion(SynchronizationImple.java:114) at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.beforeCompletion(TwoPhaseCoordinator.java:247) at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.end(TwoPhaseCoordinator.java:86) at com.arjuna.ats.arjuna.AtomicAction.end(AtomicAction.java:216) at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commit(TransactionImple.java:240) at org.jboss.ejb.plugins.TxInterceptorCMT.endTransaction(TxInterceptorCMT.java:501) at org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT.java:361) at org.jboss.ejb.plugins.TxInterceptorCMT.invoke(TxInterceptorCMT.java:181) at org.jboss.ejb.plugins.SecurityInterceptor.invoke(SecurityInterceptor.java:168) at org.jboss.ejb.plugins.LogInterceptor.invoke(LogInterceptor.java:205) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invoke(ProxyFactoryFinderInterceptor.java:138) at org.jboss.ejb.EntityContainer.internalInvoke(EntityContainer.java:527) at org.jboss.ejb.Container.invoke(Container.java:960) at org.jboss.ejb.txtimer.TimedObjectInvokerImpl.callTimeout(TimedObjectInvokerImpl.java:99) at org.jboss.ejb.txtimer.TimerImpl$TimerTaskImpl.run(TimerImpl.java:561) at java.util.TimerThread.mainLoop(Unknown Source) at java.util.TimerThread.run(Unknown Source) In the following example the timer works correctly on the state node but fails on the superstate timer. Also, it seems that the timer fires for both sub-states (the message is reported twice). When I remove one of the substates the exception still occurs with the message reported once. <state name="State 1"> <timer duedate="20 seconds" repeat="20 seconds" name="late leaving"> <script> System.out.println("What are we waiting for ? "); </script> </timer> <transition to="Moving" name="depart"></transition> </state> <super-state name="Moving"> <state name="Stopped"> <transition to="Started" name="start"></transition> </state> <state name="Started"> <transition to="Stopped" name="stop"></transition> </state> <timer duedate="30 seconds" repeat="30 seconds"> <script> System.out.println("We're late "); </script> </timer> <transition to="end-state1" name="arrive"></transition> </super-state> -- 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-2602) jBPM , Drools, Seam 2.2 - Transition issue

by Gary Lamperillo (JIRA)

jBPM , Drools, Seam 2.2 - Transition issue ------------------------------------------ Key: JBPM-2602 URL: https://jira.jboss.org/jira/browse/JBPM-2602 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 3.2.7 Environment: Seam 2.2, jBPM and Drools 5 Reporter: Gary Lamperillo When using the DroolsDecisionHandler, only one transition from a rule is allowed, when a second transition is used, the following error is received: [ProxyWarnLog] Narrowing proxy to class org.jbpm.graph.node.EndState - this operation breaks == The error should not be received, since the transition is very similar, two rules have been created. When only the first rule is used the one transition works fine. the addition of the second rule with the second transition from the same package in the working memory causes this issue. here is the process definition: <process-definition name="jbpm_to_rules" xmlns="urn:jbpm.org:jpdl-3.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:jbpm.org:jpdl-3.2 http://jbpm.org/xsd/jpdl-3.2.xsd" > <start-state name="start"> <transition to="approval"> <action expression="#{bpmCreditList.start}"/> </transition> </start-state> <decision name="approval"> <handler class="org.jboss.seam.drools.DroolsDecisionHandler"> <workingMemoryName>creditRulesWorkingMemory</workingMemoryName> <assertObjects> <element>#{creditScore}</element> </assertObjects> </handler> <transition name="not-preferred-customer" to="done2"> <action expression="#{bpmCreditList.transitionNPC}"/> </transition> <transition name="modified-score" to="modified-score"> <action expression="#{bpmCreditList.approved}"/> </transition> </decision> <end-state name="done2"> <event type="node-enter"> <action>expression="#{bpmCreditList.end}"/> </action> </event> </end-state> <end-state name="modified-score"> </end-state> <task-node name="done" end-tasks="true"> <task name="nopreferred" description="Review order" > <assignment pooled-actors="reviewers"/> </task> <transition name="done2" to="done2"/> </task-node> </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-2633) Migration guide between supported versions

by Alejandro Guizar (JIRA)

Migration guide between supported versions ------------------------------------------ Key: JBPM-2633 URL: https://jira.jboss.org/jira/browse/JBPM-2633 Project: jBPM Issue Type: Task Security Level: Public (Everyone can see) Components: Runtime Engine Reporter: Alejandro Guizar One customer has brought to my attention that migrating between jBPM 3 maintenance releases is an uncertain procedure due to the lack of a formal migration guide. jBPM should provide documentation on how to upgrade from one supported version to another (e.g. from 3.2.2 to 3.2.5.SP5 to 3.2.8). -- 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-2656) JAAS configuration within jBPM 3.2.8 not in sync

by MohReece (JIRA)

JAAS configuration within jBPM 3.2.8 not in sync ------------------------------------------------ Key: JBPM-2656 URL: https://jira.jboss.org/jira/browse/JBPM-2656 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.8 Reporter: MohReece In the jboss-service.xml file (from the /deploy/server/default/deploy/jbpm/jbpm-service.sar/META-INF/ directory) the name attribute of the jaas:application-policy tag is set to 'jbpm-console'. In the jboss-web.xml (from the /deploy/server/default/deploy/jbpm/jsf-console.war/WEB-INF/ directory) the value for the security-domain tag is set to 'java:/jaas/soa'. This means that when the contents of the /deploy/ directory are copied as-is to an appropriate directory on an application server (as tested on JBoss EAP 4.3) it will not be possible to log in at the jBPM console. It is simply solved by synching these two values (e.g. set the jaas:application-policy tag name attribute to 'soa'). -- 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-2692) Still problems with variables of Serializable objects

by Mauro Molinari (JIRA)

Still problems with variables of Serializable objects ----------------------------------------------------- Key: JBPM-2692 URL: https://jira.jboss.org/jira/browse/JBPM-2692 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.6.SP1 Environment: jBPM 3.2.6.SP1 embedded into a web application Reporter: Mauro Molinari There are times in which when calling org.jbpm.context.exe.VariableInstance.getValue(), the proprty token is null. In this case, if the variable object is of a Serializable class and this class is in the PAR, calling getValue() will fail with a ClassNotFound exception if the process class loader is not the one who loaded the SerializableToByteArrayConverter class. This is because the method org.jbpm.context.exe.converter.SerializableToByteArrayConverter.revert(ByteArray) (without the token) is called and a plain ObjectInputStream is used to do the deserialization. I don't have a simple test case to reproduce, but this is what I am doing: - my webapp application is retreiving all the logs associated to a ProcessInstance using org.jbpm.db.LoggingSession.findLogsByProcessInstance(long) - it is iterating over the collection and, for each ProcessLog instance, it is retreiving the variable instance values (for example: org.jbpm.context.log.VariableCreateLog the method org.jbpm.context.log.VariableLog.getVariableInstance() is called; for a org.jbpm.context.log.VariableUpdateLog the methods org.jbpm.context.log.VariableUpdateLog.getOldValue() and org.jbpm.context.log.VariableUpdateLog.getNewValue() are called and so on) - a ClassNotFoundException is launched; the class loader in use is that of the webapp, so it's normal that the class of the variable value cannot be found, since it is a serializable class provided by the PAR. I don't know why token is null: should it be restored by Hibernate? Looking at org.jbpm.context.exe.VariableInstance the only explicit code that sets the token property is in org.jbpm.context.exe.VariableInstance.create(Token, String, Object). -- 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-2791) jBPM variable mapping does not map correctly an empty String.

by Marek Baluch (JIRA)

jBPM variable mapping does not map correctly an empty String. ------------------------------------------------------------- Key: JBPM-2791 URL: https://jira.jboss.org/jira/browse/JBPM-2791 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.7 Environment: DATABASE: Oracle10g Reporter: Marek Baluch If I define the following variable mapping between ESB and jBPM (code bellow) and the mapped value (e.g. from ESB to jBPM) is an empty String then the result is null. <bpmToEsbVars> <mapping bpm="theBody" esb="BODY_CONTENT"/> </bpmToEsbVars> <esbToBpmVars> <mapping esb="BODY_CONTENT" bpm="theBody"/> </esbToBpmVars> The problem may lie in hibernate (http://opensource.atlassian.com/projects/hibernate/browse/HV-13). Also my test has shown that if I persist an object with some field set to an empty String then the object returned from the oracle10g database has the field value equal to null. -- 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
