Hi all,

Am I the only one getting this after some view has been moved to new
location?

I believe this is related to bug 345343
what eclipse version are you on? I can't reproduce it on Juno M6.

Hi,

I got the same error on Juno M6.

--

Version: 4.2.0
Build id: I20120315-1300

OS : Windows Vista 64bit

--

1.
I created e4 Application Project. All settings are default.

2.
Added DnD Addon to Application.e4xmi and set the dependency to org.eclipse.e4.ui.workbench.addons.swt.

3.
Added two Parts (Part1, Part2) to Application.e4xmi.
PartSashContainer > PartStack > (Part1 & Part2)
Created corresponding classes for Parts.

4.
Run the Product.

Separate Parts (No Error).
Put back the Part(No Error).
Separate Parts(Got Error).
