I create activiti diagram , name is Myprocess.activiti. I save this diagram. Two files *.bpmn20.xml and *.png came out. *.bpmn20.xml can not open with graphical notations. i open *.bpmn20.xml with txt. i find this file included the info of graphical notations. Can the *.bpmn20.xml display the graphical notations?
You can generate the graphical representation of a deployed .bpmn20.xml file using ProcessDiagramGenerator.
As announced here: http://forums.activiti.org/en/viewtopic.php?f=8&t=3563, .activiti-file will be removed in future. -> in future versions, it should also be possible to generate the graphical representation in designer
