New BPMN2 editor: alignment on centre causes exception and cannot be undone --------------------------------------------------------------------------- Key: JBPM-3087 URL: https://issues.jboss.org/browse/JBPM-3087 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Eclipse Reporter: Gary Brown Assignee: Kris Verlaenen Fix For: jBPM 5.x Created diagram, setup two participants, dragged start event, dragged choreography task, assigned participants, created sequence link from start event to choreo task, added another choreo task, selected all three nodes and selected the alignment->centre option on the context menu. Firstly the centre option is vertical - was not clear whether vertical or horizontal. The error log then had two errors which appear to be the same: eclipse.buildId=I20100608-0911 java.version=1.6.0_18 java.vendor=Sun Microsystems Inc.
