After some use of Papyrus and some commands applied on model explorer, there is a NPE that appears. Then behavior becomes really unstable and the only option is to close project and close Eclipse. If you do not close Eclipse, other projects face strange behavior ... note: appreared with last download = nightly 1700 release. note 2 : I recently upgraded modisco from update site with release 201109150824. Perhaps the issue comes from this last release? stack trace: java.lang.NullPointerException at org.eclipse.swt.widgets.CoolBar.getWrapIndices(CoolBar.java:646) at

I couldn't reproduce the issue recently. Do you still meet this problem in the latest releases?
Neither do I. Seems to have disappeared. Closed
