Upgrading domino server from 6.5.5 to 7.0.2 release i've introduced a new dwa error: "Entry non found in index" while trying to select names from address book ("To:" button on new memo page).
As described here:
the problem is that my dwa template is still related to an old domino release (6.0).
Since i can't upgrade the dwa template, due to some personalizations and due to much users that still use old client version, the solution is to put a new view into the old template:
The view is named ($PeopleGroupsFlatExt) which you can get from the new dwa template or simply create by copying and renaming the ($PeopleGroupsFlat) view.
