domain aliases and Google App Engine

Question

I have a Google Apps domain at www.openstv.org that I use for email and a website.

I recently created a Google App Engine app at stv.appspot.com and it can also be accessed at opal.openstv.org.

I would like to:

1. Use www.opavote.org for my Google App Engine app instead of opal.openstv.org, and
2. Have opavote.org be a domain alias of openstv.org so that I don't have to maintain two Google Apps domains.

Two stackoverflow questions suggest that this is possible:

1. Google App Engine on Google Apps Domain
2. Google App Engine and domain name

But other reputable information suggests that it is not possible: Issue 638

I've tried to do this, but I can't get it to work. Is there an explanation for this apparent contradiction?

EDIT: Adding what I tried in response to Nick's comment.

From App Engine Dashboard:

1. Go to Application Settings
2. Click Domain Setup
3. Enter opavote.org -> "Sorry, you've reached a login page for a domain that isn't using Google Apps. Please check the web address and try again."
4. Click back and enter openstv.org -> Takes me to Google Apps for Openstv.org
5. From Google Apps Dashboard for OpenSTV.org -> stv settings (my GAE app) -> Click add new URL
6. I'm allowed to enter a subdomain of openstv.org (e.g., opal.openstv.org) but I am not allowed to use the opavote.org domain (there is no dropdown menu for the domain).
7. Go to Google Apps -> Domain Settings -> Domain Names and see that opavote.org is listed as a domain alias and is verified in two ways (DNS record and uploading file). No other options here.

Answer 1

If you've added 'opavote.org' as an alias, it should be showing up in the list - this sounds like a bug with Apps. Have you tried removing it and re-adding it? If that doesn't work, you may need to file an issue with the Apps team. It's definitely possible to do this - I'm running apps off alias domains myself.
