Problemas con Fork/Join
-----------------------
Key: JBPM-2570
URL: https://jira.jboss.org/jira/browse/JBPM-2570
Project: jBPM
Issue Type: Task
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 4.0
Environment: Windows xp, eclipse Version: 3.4.2 , using hibernate and spring.
Reporter: Sebastian Castellanos
Fix For: jBPM 4.x
Estoy teniendo unos problemas con los Forks/join cuando tengo swimlanes asignados. y no doy en el clavo aún. Quizá se te ocurra algo.
Tengo un grafo sencillo, con 5 tareas. tarea 1, tarea 2 tarea 3 , tarea 4 y tarea 5. tambien tengo un fork y dos joins.
La situacion es asi:
Arranca el proceso y lo primero que hace es lanzar un Fork que ejecuta 3 tareas, Tarea 1 , 2 y 3. las cuales tienen diferentes swimlanes asociados.
de esas 3 tareas, la Tarea1 y la Tarea2 convergen en el Join 1, que el join 1 continua el hilo hacia la tarea 4.
La tarea 4 tiene una transaccion a un Join 2, que se encarga de cerrar la tarea 3 (inicialmente lanzada con la Tarea1 y la Tarea2, pero queaun no esta cerrada).
una vez finaliada la tarea 3 y la 4 deberia continuar el flujo.
Teoricamente, parece estar bien. Practicamente, funciona el Fork/Join si no le asigno swimlanes. Pero al momento de asignarle diferentes swimlanes las 3 tareas iniciales T1 T2 y T3 da problemas, no me esta dejando cerrar el primer Fork. Porque la Tarea1 y la Tarea2 tienen diferentes swimlanes (me esta dando un error de calve foranea entre la tabla de las tareas activas y la de los swimlanes). Por lo que veo, quiere borrar de la tabla de tareas activas una tarea luego de terminarla, pero no la borra de la tabla de swimlanes como deberia y surge el error de la clave foranea.
Este es el error.

Fix For: jBPM 4.x
When I want to instanciate my project engine, I have an exception. It was working in 4.0 and 4.1 but not in 4.2.
I think it is because a field must be setted in jbpm but I don't which.

jBPM4/Spring: unintended wiring PropertiesFactoryBean to RepositoryCacheImpl.deployments field
----------------------------------------------------------------------------------------------
Key: JBPM-2478
URL: https://jira.jboss.org/jira/browse/JBPM-2478
Project: jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 4.0
Environment: Windows XP Service Pack 3, JDK 1.6.0_13, Eclipse Galileo JavaEE, jBPM4
Reporter: Michael Feichtegger
If you define a spring bean (<bean name="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean" ) this bean will be an instance of java.util.Hashtable (java.util.Properties) at runtime.
During jBPM initialization various ObjectDescriptiors create instances they describe. So do the descriptor of org.jbpm.pvm.internal.repository.RepositoryCacheImpl.
After creation the auto-wire mechanism tries to set-up the fields. In case of RepositoryCacheImpl there is just one field: Map<String, Object> deployments.
The "configProperties" bean will be found in the SpringContext since java.util.Hashtable implements java.util.Map and the field "RepositoryCacheImpl.deployments" will be set because there is just one object of the requested type (java.util.Map). The isAutoWireEnabled attribute is set to "true" (hardcoded) at RepositoryCacheBinding.
This behavior causes a NullPointerException when deleting a deployment
RepositoryCacheImpl.java line 45
deployments.put(deploymentId, null);
That statement works on java.util.HashMap (created when instantiate RepositoryCacheImpl) but not on java.util.Hashtable.
That behaviour might influence several other components.
