I have tried with 3 different browsers and changing the email address in an existing contact record results in the following error.
Error
Error messagePDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '' for key 'name': INSERT INTO {users} (uid, mail, created) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2); Array ( [:db_insert_placeholder_0] => 73 [:db_insert_placeholder_1] =>
firstname.lastname@someplace.gov [:db_insert_placeholder_2] => 1339012572 ) in drupal_write_record() (line 7013 of /home/government/www/services/includes/common.inc).
Reloading the page submits the update correctly. I flushed site cache and browser cache to be sure it wasn't old form data or temp files. Anyone else have the same issue? I haven't tried in the sandbox but I can if need be.
Thanks.
