Simple process with ServiceTask cannot be deployed

Hi,I'm using Activiti 5.1, running on MacOS, Java 6, and using the Activity Modeler in Safari. Activiti itself and all tooling looks very interesting, but I have some issues I can use some help with:1. I have created a very simple process in the Modeler consisting of a start event, a service task an

But each time I save the process in the Modeler, its ID changes

would be good if signavio connaisseurs could confirm if this is expected behavior

Hi Bram,

Is there a reason you especially want to use the Modeler instead of the Designer.
From your description it looks like you are already developing Java code to run the process definition. So the Designer would be a good match for that kind of development.
And also you can configure a Java class with your service task and define a process ID yourself.
The execution listener is something we are working on, and probably will be available in the next release.
Also available in the next release of the Designer is a functionality to import models from the Modeler to the Designer.
So, if you want to execute your processes in your own Java application I would recommend using the Designer instead of the Modeler.

Best regards,

Hi Tijs,

We had a hard time getting the Designer Eclipse plugin to work in Eclipse. Apparently, Java6 is required for this plugin, as I read here: http://forums.activiti.org/en/viewtopic.php?f=8&t=677. Running Eclipse on Java6 on MacOS used to be a problem too (http://blog.kischuk.com/2008/05/08/running-eclipse-on-macbooks-with-java-6/), but the 64 bit version of Eclipse Helios runs fine on Java6.

Anyway, I tried the Designer plugin and found out that, as you mention, there's no way (yet) to configure execution listeners. You'll have to do that by manually editing the xml. Saving the model again overwrites these changes, so there's no way to perform round-trip-editing.

Besides, the Designer palette seems to offer fewer BPMN components than the Modeler and I'm not sure yet this (sub)set will be enough to model our workflows.

Thanks for you reply,
Bram

Hi Bram,

If you are using an updated os x snow leopard Java 6 is installed by default so that should not be a problem.
You are right about the execution listeners and the overwriting. We are currently looking into this from two sides. I'm adding the execution listener configuration. This will be in the next release for sure. We are also trying to support round-trip in the designer and I hope this will be ready for the next release.
We chose to implement fewer BPMN components, because we stick to what the Activiti Engine supports. We currently are missing the boundary timer event, which is supported in the Activiti Engine, but that's also on our list. Let me know if you run into limitations of the Designer for functionality you really need. We can always prioritize our work based on your feedback.

Best regards,
