I am using Designer 2.0 that came with JBPM5.2 package. The Designer war file that is
deployed on the server is designer-2.0-jboss7.war
Form the designer toolbar on the top there is an icon which has 2 options : Import from BPMN2 and Import from JSON.
I select import from BPMN2. Then I navigate to the actual BPMN file and click on import. It comes back with a pop-up
dialog that just has the RED cross meaning there is an error.
