Designer - Access right on a column

Hi,

In the Web designer I created a grid to dispay an Org collection (created basedon the org table)

When I goto the page do display my org, I got the following :

(Rôle métier = Ident_Org, Libellé = ShortName,Description = description)

I think the message is understandable : ShortName field is hidden but I really don't know where should it be modified.

In the designer I modified the access right on the corresponding table and column column (see below)

Access right on the table

Access right on the column

But I still got the same message <hidden: ...>

Do you have any idea what's goin on ? Which group permission should I add if I want everybody to see this column value ?

thanks again for your help,

Regards,

Steph.
