Hello! I try to use Activity Designer on my PC and have a problem that eclipse cannot redraw screen on my actions. The story is the same on Indigo and Kepler. Hack is to press "close eclipse" then cancel, but i need to do design blind. That makes plugin unusable on my PC. It's a eclipse problem or activity plugin problem? Also in console i have some warnings log4j:WARN No appenders could be found for logger (org.activiti.bpmn.converter.BpmnXMLConverter). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info. Before opening bpmn diagram everything worked fine.

It seems that this issue is related with SWT/GTK and the underlying printing system, or at least with some dependency between them only observable when using Graphiti (at least in my case). CUPS is not running on my system by default, but I have it configured… I do not know if this is a regression, nevertheless the solution reported at https://bugs.eclipse.org/bugs/show_bug.cgi?id=215234 seems to work.
So, I just added <code>-Dorg.eclipse.swt.internal.gtk.disablePrinting</code> to <code>eclipse.ini</code> and the problem is solved.
