1272996 - Summary dialog: attendees should not be displayed inside a listbox

Status: NEW

(Calendar :: Dialogs, defect)

Description

[Decathlon]

Followup bug from bug 1271662.

As discussed in bug 1271662 comment 14 and following, would be better if the  attendees were displayed in the Summary dialog without the listbox because it looks like the attendees are somehow editable.

Steps to reproduce:
- create a new event for a given calendar, add some attendee, save&close the dialog;
- set the calendar to read-only;
- open the event previously created;

--> the Summary dialog displays all the attendees inside a white background box.

See screenshot in bug 1271662 comment 17

to see how the dialog should be.
