Link to validation result bound to a proxy URL does not lead to a valid page

When you validate a message in the proxy and then copy the link to that message in a test step, the result of the validation in EVSClient is displayed in the test step. Clicking the button (green or red circle) should lead you to the validation report in EVSClient but it is not the case, we are currently redirected to http://sake.irisa.fr/EU-CAT/testing/test/test/not+performed.
Same behaviour for the link when you upload a file to the test instance.
See http://sake.irisa.fr/EU-CAT/testing/test/test/TestInstance.seam?id=49087 for example
