"This application ID or version is already in use" Error

[Sagie Maoz]

Hi,

I've just started learning to use App Engine, and trying to figure out
my way into the service...
I created an account, but when filling the "Create an Application"
form at http://appengine.google.com/start/createapp , All I get is the
error message:
This application ID or version is already in use

I have read in past discussions that there was a problem with the
"Check Availability" button, but this happens to me for every input,
even for some made-up strings that I'm pretty sure are available.

Am I doing something wrong? Is the service open to new applications at
all?

Thanks

Hi,

I don't know of any problems with the app id verifier. App Engine
checks app ids against the Gmail namespace, so any app id that is
already taken as a Gmail address will only be available to the owner
of that address.

The net result is that many desired app ids are not available.

I have heard of this problem. One workaround that has apparently
worked in the past is:

1. Log out of Google app engine.
2. Close browser (all windows - make sure you have quit the browser
app).
3. Reopen browser.
4. Try again.

Boson, your workaround seemed to solve my problem. Thanks!

Is there a way to report this to the Google team?
