URL link (process tab) by mail

Hello,

I have created a mail connector in a service task with a link to the process tab of the portal. But I have a visual problem when I click on it, see abrove:

My result by clicking:
http://www.hostingpics.net/viewer.php?id=783765testURL02.png
==> the tabs “tasks”, “cases” and “processes” are not visible on the top and the profile is not selected “select profile”.

What I must obtain normally with a normal navigation on the portal:
http://www.hostingpics.net/viewer.php?id=958387testURL03.png
==> Here I can see the 3 tabs and the profile is select as “user”. On this account there is only one kind of profile.

Thank you very much,
Sylvain

I have forgotten to put my code:

StringBuffer buffer = new StringBuffer(“you can launch the process here: <a href="”);
buffer.append(stringAdrServeur);
buffer.append(“/bonita/portal/homepage#?_p=processlistinguser&_pf=0”);
buffer.append(“">process blabla

”);

No answers?
