When I'm starting up the inner 4.0 SDK, I get exceptions from the simpleide JDT bundle:


Caused by: org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'org.eclipse.emf.ecore.impl.DynamicEObjectImpl@71467146 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@6b276b27 (name: Command) (instanceClassName: null) (abstract: false, interface: false))' is not legal.

I can't reproduce this locally - did you updated the model.simpleide bundle, I check in changes yesterday to reflect you contribution changes

Yes, I'm up to date with HEAD.

To repo I've got most of e4 ui/css/core checked out in my workspace, as well as all of simpleide. I create an Eclipse Application to launch the 4.0 SDK and include all workspace and target plugins.  Then I delete the launch-config-workspace and launch.

I've now set up my workspace completely the same but I'm unable to reproduce this.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

This is a mass change to close all e4 bugs marked with "stalebug" whiteboard.

If this bug is still valid, please reopen and remove the "stalebug" keyword.
