Description Missing name CLA 2012-10-22 07:18:11 EDT 
About every week I startup eclipse and am greeted with the default workspace with all my changes lost. This is quite annoying.
It appears to be connected to the error below:

Comment 2 Kentarou Fukuda CLA 2012-11-17 06:49:51 EST 
Does this bug relate to EMF?
Comment 3 Ed Merks CLA 2012-11-17 07:06:30 EST 
No, the exception shows this is caused by this not liking the value that's being deserialized.

org.eclipse.e4.ui.model.application.ui.impl.ElementContainerImpl.setSelectedElement(ElementContainerImpl.java:164
Comment 4 Michael Suhr CLA 2013-06-03 02:41:31 EDT 
Happen also to me. I have a way to reproduce this. If you detach a window for Call hierarchy/Search and History e.g. then there will be saven another "TrimmedWindow" in .xmi file. The attribute "toBeRendered" is false an so the UIBuilder check if the selected element is rendered which isn't.
I don't knw why Eclipse store that the selectedd element is in the new window but if I set the "ToBeRendered" attribute to true my worbench is loaded without any error.

Hope it helps to find a solution.
