Hi Joram,

I am using jbpm4.2 in our project. I am trying to log manual task entry and exit information in log. It is easy to use event-listener to each transition( transition which takes the process flow to a manual task and transition which takes the out the process flow the manual task). I want a common place(event listener) which will be called whenever a manual task is created,assigned and exit. Do you have any idea how to implement this.

Regards,
Arup

Hi Joram,

maybe you can help me on this:

How is it possible to create collections of already created (java-)tasks within the Eclipse-jBPM-Editor or even better within the Signavio-Editor.

What I mean by this is to reuse already created (java-)tasks with a drag&drop, because in our process flows many tasks need to be done again and again at different process stages. So I don’t want to create the same tasks again and again (even not copying them from somewhere-else).

I imagine something like a list of (java-)taks icons to the left which I can pick from.

Do you have any idea how to do this or have heart of anyone doing somehting similar ?

Your help is very appreciated.

Regards, Robert.

Hi Joram,

I’m implementing a document review process using jBPM, and found your blog quite helpful.

I was wonderign if you could help me with your expertise. Basically I have a task, called “Read document”, that derives from another task, which is “Assign Reviewers”.

I have to create several instances of “Read document”, (exactly N task instances, for N reviewers), and after each one finishes reading,
(hence, needing synchronization), I would like to give the final verdict to the document automatically.

The problem is I found that multiple instances with synchonization isn’t supported by jBPM, and I was wondering if I have any alternatives to implement this behaviour.

Thank you in advance.
Fabio

I cant post to JIRA but I wanna tell you I need support for Tomcat. Especially I wait for el-api – juel conflict resolution. It may be very easy like to remove juel.jar dependency from jbpm. juel-impl should be sufficient and then there is no conflict. Please!!!! I want to use jbpm and my fav. environment is maven and tomcat/jetty maven plugins.
Great soft anyway!

@Geronimo: I’ll be posting the complete demo zip today, then you can check what is different with your setup.

Which JBoss version did you use? I’ve built the demo on 4.2.3, but I’m not sure if its directly portable to 5.x (altough it shouldn’t be hard to do)
