In my Identity Vault, I have a user called Brigitte.

In her User Profile, in section "Business Info/Organization",
her manager is Frederic and her assistant is Nathalie.
Her direct reports are Cindy and Brenda.

If I want to see the Organizational Chart via iManager, I can see it
without problem.

But, if I log on UserApplication, if I search Brigitte and if I display
details of Brigitte,
when I click on "Display Organizational Chart", I have the following error
in the logs :

16:35:34,828 ERROR [EboPortalAggregationServlet] no portlet provided in

Do you have an idea of the reason why I can not access to organizationnal
chart ?
Many thanks in advance for your help,
