todo.jpdl.xml - Error opening the editor (jBPM Graphical Process Designer) -------------------------------------------------------------------------- Key: JBIDE-860 URL: http://jira.jboss.com/jira/browse/JBIDE-860 Project: JBoss Tools Issue Type: Bug Components: jbpm Affects Versions: 2.0.0.Beta3 Environment: Eclipse Europa / JBoss Tools (2.0 beta3) Reporter: Joachim Neubert Attachments: seam_todo1.jpg, seam_todo2.jpg When I try to open the todo.jpdl.xml, I get a message "Convert to 3.1.x format?" ("older GPD version was detected"). When I confirm the default action "Convert And Open", I get: Error opening editor Reason: null argument ("Details" below) With a new process definition, I get the same error: New -> JBoss jBPM -> Process Definition -> Process Name: test1 creates: test1 +- gdp.xml +- processdefinition.xml Opening the processdefinition.xml in the jBPM Graphical Process Designer results in exactly the same
