Attached sample project and necessary instruction to simulate this error on the originating forum.

Abhishek Maheshwari 2013-04-03

I think we have already fixed this in 4.0.x and trunk. Can you simulate the attached zip on forum and update the jira?

Can someone confirm please that the fix is in place and which release the fix is available in? Thanks.

We were waiting for Field to verify that this solution did resolve the issue.None the less the unverified fix is in 4.0.1

Aurelien Broszniowski 2013-06-13

I tested this with 4.0.1-RC and the issue is fixed
