NullPointerException when trying to open properties view [message #1819238]

Hello,

after updating Eclipse to version 2019-12 I cannot open the Properties view for model elements shown in a Sirius based model editor. Am I the only one, is my system somehow broken and the Eclipse update wasn't the reason for this change?

I also experienced this after downloading a fresh eclipse-jee-2019-12-R-win32-x86_64, installing ECoreTools 4.0 and Sirius 6.2, installing the latest updates and create a new Modeling project with an .ecore file in a new workspace.

eclipse.buildId=4.14.0.I20191210-0610
java.version=1.8.0_231
java.vendor=Oracle Corporation

Hi,

This was a regression introduced in EEF 2.1.3 by the change for https://bugs.eclipse.org/bugs/show_bug.cgi?id=550436. The fix for this NPE has just been merged on master (https://git.eclipse.org/r/c/155809/) and will be included in the next EEF release.

Sorry for the inconvenience.
