[jboss-user] [jBPM Users] - JBPM 4 dynamic timer duedate
What is the best practice for setting dynamic duedates on timers in jbpm4? I have a use case were I need to signal a transition at a specific date/time depending on a variable(java.util.Date) in the business process. In the example below start is a Date variable on the process and this fails due to a classcast exception. This way of setting a dynamic duedate seems to be supported in jbpm 3.x. (e.g. http://docs.jboss.org/jbpm/v3.2/userguide/html/businesscalendar.html). | | | | | .. | | Part of stacktrace: | ERROR [ExecuteJobCmd] exception while executing 'ExecuteActivityMessage[11]' | | java.lang.ClassCastException: java.util.Date cannot be cast to java.lang.String | at org.jbpm.pvm.internal.job.TimerImpl.setDueDateDescription(TimerImpl.java:76) | at org.jbpm.pvm.internal.model.ScopeInstanceImpl.createTimer(ScopeInstanceImpl.java:303) | at org.jbpm.pvm.internal.model.ScopeInstanceImpl.initializeTimers(ScopeInstanceImpl.java:323) | at org.jbpm.pvm.internal.model.ExecutionImpl.createScope(ExecutionImpl.java:262) A quick peak in the jbpm source code seems to reveal that the wanted behavior is not possible, hence the starting question. Do i need to create and persist the timer manually? (e.g. node enter event listener) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4270032#4270032 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4270032 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [jBPM Users] - Re: Accessing the current task of a ProcessInstance and/or h
Have you found a solution for this? We are have the same use case were we have a process with a lot of subprocesses that create several tasks and we need a simple way to query for all the tasks for the process including tasks generated by its subprocesses. The interfaces have some limitations and we have seen the need to create our own custom repositories that works over the jbpm tables for some of these queries using oracle specific features to do queries over tree structures. jBPM seems very configurable and I think many projects will need to extend the basic service interfaces and the out of box query support using their own commands and extensions. The service interfaces cover the basic and most used features and I can understand that the jBPM development team wants to keep them slim. You could create a custom command, but for me it seems like you will not come away from a downcast if you for example need to create custom queries using the hibernate critereia api.

We are also running jBPM 4 in spring + JTA and we are not having the same problem as you describe. We start our spring context from a simple war project that uses a parent spring context loader at the ear level (we are also using ejbs). When the application is started the jobexecutor is started automaticly as we have setup spring to execute the buildProcessEngine factory method on SpringJbpmConfiguration at spring startup (lazy-init=false).

[jboss-user] [jBPM Users] - Jbpm 4.1 ProcessEngine.execute() / CommandService
How can one access the commandservice to execute custom commands in JBpm 4? The ProcessEngine interface has a execute() method that tries to get the "user.command.service" wiredefinition (which is null by default), so the question is: what is the best practice to run custom commands in JBpm 4? Am I missing something obvious in my configuration? I'm using a Spring setup.

[jboss-user] [jBPM Users] - Re: How to get history variables and processInstanceId from
Is it possible to get the name of the task that was finished from the history? To be able to get the name of the finished task one have to first find the task in the HIST_TASK table, and then look it up in HIST_ACTINST (activity_name) table too? E.g. is there any plans to simplify the programming model against the history tables to traverse relations? E.g. from a HistoryTask instance to its related HIST_ACTINST row?

"kukeltje" wrote : Yes, use a plain fork-join for this. I still have to admit that I think the task-node approach is much easier to work with. The jbpm documentation should have more information about differences from the jbpm 3.x way to model stuff. E.g. to associate tasks with a state. How would you model a simple scenario as this: start -> Registered (state) with 2 tasks that are created when the state is entered, one that MUST be performed, and one that is optional -> Handle, state with several tasks.

Im quite new to BPM and jBPM but I want to re implement an existing jBPM 3.x process in jBPM 4, but the existing process definition uses more or less only task-nodes. All the 3.x projects I've seen seems to use task-node definitions extensively and there is no examples/documentation in jbpm 4 that covers how to achieve the same type of behavior. Seems like what im after is grouping and/or fork/join. The behavior that I want is more or less like this: When entering a certain state (task-node) I want to create 5 tasks that have to be done to transition to the next state.

Bumping this. Is there any equivalent for task-node in jbpm 4?
