This resulted in a duplicate domain: user@domain.tld@domain.tld, which of course is invalid. Instantbird could be smarter and detect if the entered username contains an @ sign. If the domain part matches the Domain field, strip it, otherwise complain. Or it could just not allow @ signs in the Username field. Hitting the @ key in Username could trigger focussing the Domain field.

Having the separator character used to change the focus to the next field was something I wanted to have when we split the username field in several parts. I think we didn't do it because the '@' can be valid inside the "user" part of an XMPP id. If I remember well, it's possible to use any email address with google talk, and the XMPP id becomes <email>@gmail.com, where "email" contains the '@' character. I'm not sure of this. Someone or something made me believe this at least when we implemented the username split. I would love if it could be proved wrong! :)

*** Original post on bio 432 at 2010-07-04 06:54:30 UTC *** I think @s are not allowed in the user part of the address. Technically. Everything seems to be allowed as long as it is percentage-encoded (like on URLs). So an "@" can be entered as long as it gets converted to it's percentage-encoded equivalent. So far so bad. Some specs: http://xmpp.org/rfcs/rfc5122.html#use-form The IRI thing it is pointing to is here: http://tools.ietf.org/html/rfc3987#page-7 Maybe go to the next field by default and add a UI element that allows to undo it (cf Smart tags on MS Office that allow to undo automated actions) ?

Does not apply to JS-XMPP (now default) which has a separate username and domain field in the account wizard.
