Every time I select something or create something a window pops up saying "Multiple errors occurred". There are 3 errors, the first and third error say "NullPointerException" and the second error says "org.eclipse.sirius.ui.properties.internal.TransactionalEditingDomainContextAdapter.getLockStatus(Lorg/eclipse/emf/ecore/EObject;)Lorg/eclipse/eef/core/api/LockStatusChangeEvent$LockStatus;" In the error log it spams: "eclipse.buildId=4.6.3.M20170301-0400 java.version=1.8.0_111 java.vendor=Oracle Corporation BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=nl_BE Framework arguments:

Hi and thanks for your feedback. It could be related to a version mismatch, could you please give me the versions of the plugins: org.eclipse.sirius, org.eclipse.eef.ide.ui and org.eclipse.emf.ecoretools which are installed in your environment ? Did you install everything into an Eclipse SDK or through a specific package ? (Eclipse Modeling, or Obeo Designer CE)..
Hi Rien, The stack looks very strange, as in "it should not happen", and thus is a little scary. Either its a mismatch between incompatible development versions of Ecore Tools / Sirius / EEF (which would be a transient issue, probably not present when using released versions), or something really bad and unforeseen is happening. From your report I see you were using the Java package (org.eclipse.epp.package.java.product). I tried to reproduce using Oxygen RC3 version of this package, and installing Ecore Tools (which brings up the necessary parts of Sirius and EEF) from http://download.eclipse.org/releases/oxygen. I was not able to reproduce the issue. Can you give us some details of which versions of Ecore Tools / Sirius / EEF you have installed, and from which update sites? Did you also install other modeling components? Can you reproduce using the versions currently available in http://download.eclipse.org/releases/oxygen? Thanks for any addition details you can provide to help us understand and fix the issue.
Hi Rien, any update or information so that we can investigate further ?
