I also removed the dot from the sender's email, but it didn't work. Do I
also have to remove the user from Permissions list, and add it (send
invitation) again without the dot ?

The sender is not Billing administrator. The users that i tested (that
didn't contain a dot) worked without being billing admins.
Also, I believe there can only be one billing administrator right ?

The original email is at gmail.com, as well as the email that works. My app
has the federated login option selected, but it has nothing to do with the
users that send the emails.

Re: [appengine-java] Re: javax.mail.SendFailedException: Send failure:Unauthorized Sender: Unauthorized sender

[Andrei Cosmin Fifiiţă]

I removed the user and add it again, sending invitation to the address
without dot. When I accepted the invitation, i logged in typing the address
without the dot. After accepting the invitation the email was registered as
it was originally created (with a dot), so it did not work :(
I don't know what's the problem...

Re: [appengine-java] Re: javax.mail.SendFailedException: Send failure:Unauthorized Sender: Unauthorized sender

[Andrei Cosmin Fifiiţă]

I tested as Developer and Owner. The problem is that even though i invited
the user using its address without the dot, App Engine seas the original
email address, created with a dot. My code uses the address without the dot
when trying to send an email, but still, doesn't work...
The new user created for testing (without any dots) was added to Permissions
list as Developer and it worked.

[Andrei Cosmin Fifiiţă]

Well, yes, that is what i tried...  I thought it worked for some people but
i has wrong... I knew that removing the dot was actually a representation of
the same address, that's why i removed the account from Permissions, and add
it again... Anyways, this is somehow annoying so i hope they'll fix the
problem soon :)

Re: [appengine-java] Re: Best performance for deleting and inserting entities

[Andrei Cosmin Fifiiţă]

Thanks for the feedback.
Btw, using low level api should have better performance than using jdo ? And
also, (regardless of jdo or low level api) making persistent a collection of
entities is *significantly* better than one at a time ?

Re: [appengine-java] Re: Synchronized reads/writes on a memcache variable

[Andrei Cosmin Fifiiţă]

I was thinking about that (increment/decrement)...
But, first, if the tasks read the value of the variable that needs to be
incremented, isn't there a posibility that all tasks will read the same
value at the same time and then increment it in the same time ?

Re: [appengine-java] Re: Synchronized reads/writes on a memcache variable

H, super...
I was thinking of smth like (val mod 2) == 0/1 (true/false), but the lock
reading wasn't safe.
Thanks!
