Now I am seeing that it is a known "bug" or feature with Google Calendar.
https://code.google.com/a/google.com/p/apps-api-issues/issues/detail?id=1402It was supposed to be fixed with version 3
https://developers.google.com/google-apps/calendar/v3/reference/events#attendees.displayNameIt is still an issue. Apparently it is addressed grammatically. For EA I am thinking setDisplayName should tell Google Calendar to show the name instead of an email address. I see that "attendees[].displayName" is an optional command in the absence there of the email is displayed. All I am getting is email addresses. So, now it is looking like it may be a coding issue again. I have learned that an exception to this is if the attendee is a registered gmail user. In that case the gmail user's name will show up.
This is a problem because if I see
fluff...@yahoo.com I have no idea who this client is and cannot prepare for them. So, I will continue trying to figure this one out.
