Link in approval notification mail is wrong

Hello all,

I have setup the workflow of role approvals in IdM. Everything works fine appart from the link that is sent by mail to approve the requests. The page opened does not contain any approval request:

I receive the following mail when a user requests a new role:

but when i click on the link, it opens the following URL:

So it is pointing to the right system and the right URL, so my guess is that MX_GUI_URL_PREFIX is well defined, but for some reason it does not show the task to approve. If i logon to the IdM interface i could see the approvel tasks in the "ToDo" page.

Any idea ?
