Did you know there’s a new release of Activiti out? Okay, it has been out since March but I’m just now getting around to saying something about it. I haven’t given the entire thing a thorough evaluation, but if you are using the Activiti Designer Eclipse plug-in, you’ll be happy to know that you don’t have to fool with two files for each process definition any longer (three files, if you count the PNG). Instead of a .activiti file and a .bpmn20.xml file, there is just a single .bpmn file.
The new Designer also supports modeling sub-processes. And, it is easier to work with boundary events than it was before.
If you have existing Activiti process definitions, you can open your old .bpmn20.xml files and save them as .bpmn files. Then you can delete your .activiti and .png files.
The version of Activiti embedded in Alfresco 4.0 (Community and Enterprise) is 5.7. I’m assured by the development team that processes edited with version 5.9 of the Designer will continue to work with 5.7. However, there may be some items on the palette that are not supported in older Activiti versions.
One thing to note about this release of the Eclipse plug-in: It no longer runs with Eclipse Helios. You’ll have to upgrade to Indigo.
