TYPO3 Core

When installing TYPO3 CMS 6.2 from scratch, at the step create user and import base data, you have the option to enter a username and a password for the initial administrator user. Field username is pre-filled with "admin".

- change "admin" to your own username (e.g. "firstname.lastname")
- use a short, insecure password
- click "continue" button

Message appears "Administrator password not good enough!" and form comes up again.
At this point, field username falls back to "admin".

However, the username was not the problem and from a usability perspective you would expect that valid data entered should remain. Therefore, the field should be pre-filled with the previously entered value (e.g. "firstname.lastname") rather than fall-back to "admin".

This issue occurs in TYPO3 CMS 6.2.0beta5.
