ACL Picker: double click should open a detailled view of the user or the group

Clearly speaking, the level of details offered by default by the ACL picker is not sufficient for Enterprise-wide LDAP repository. This is quite hard, excepted knowing the login name of its near collegues, to find the other resources (user or groups) and to be sure that we have not make any selection mistake.

Currently double clicking on a user or a group automatically select and add this user in the ACL panel. I think we should rather open a detailled view of the user or the group with all the possible information we could collect.

This would let the editor rapidly confirm that this is the right user or the right group composed of the right users. Currently in order to know precisely who is member of a given group, you have to login in the administration group which is only reserved normally for site administrators.

Of course such a GXT extension could also replace the current old engines in the admininstration center in order to list all members of a group or see the details of a user.

So it looks like a kind of GXT User Profile component and another GXT Group Details component which could be reused throughout Jahia. There is also a merge to do perhaps with the MySettings User Profile component (only a basic form for the moment) so that we could have one single "GXT profile" component (perhaps with different facades).
