This is the way I'm working with Activiti,
1. I'm designing my processes in Activiti Modeler.
2. It generates my .bpmn20.xml files with the process definition.
3. Then I customize the .bpmn20.xml by adding activiti:formKey and some other extensions.
However, after that, I cannot go back to Activiti Modeler and go on editing my process because after saving it I will lose the custom changes I made to the .bpmn20.xml file in step 3.
Is that the right way to work? Can I import a .bpmn20.xml file into Activiti Modeler?
Thanks.
