[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-3088) BPMN -> jPDL wizard fails if selected file is not BPMN

BPMN -> jPDL wizard fails if selected file is not BPMN ------------------------------------------------------ Key: JBIDE-3088 URL: https://jira.jboss.org/jira/browse/JBIDE-3088 Project: Tools (JBoss Tools) Issue Type: Bug Components: jbpm Affects Versions: 3.0.0.beta1 Environment: JBT 3.0 beta 1 build Reporter: John Graham Assignee: Feng Qian Priority: Critical Fix For: 3.0.0.cr1 If the resource (file/folder/project) selected when the BPMN -> jPDL wizard is launched is not a BPMN file, then the wizard does not open, failing with the exception below. Since the user selects the BPMN resource(s) to convert on the first page of the wizard, it should not matter what the current selection is when the wizard starts: eclipse.buildId=M20080911-1700 java.version=1.6.0_07 java.vendor=Sun Microsystems Inc.
