Class MailsystemDelegateMailSystem does not exist and could not be loaded

After looking at the code I suggest to rename the file MailSystemDelegateMailSystem.inc into MailsystemDelegateMailSystem.inc instead of updating the info file because the contained class actually is named MailsystemDelegateMailSystem.

Attached patch renames the file instead.

"MailsystemDelegateMailSystem" is more precise camel-casing, anyway. Works in my testing.

Patch #2 works for me too. Thanks!

#2 Works great.

Committed #2 to 3.x. Thanks!

Sorry to be the harbinger of bad news but it's not fixed yet. :-) I downloaded the package today and was dumbfounded by the error message. Being closed, the issue queue didn't bring it up, only Google helped. The file still has an uppercase S in the name and manually renaming it helped.

Sorry, this is fixed in the development snapshot of the 3.x branch, which wasn't published until now. It is not fixed in the alpha1 release that you probably downloaded.

Sorry, I am getting the same error after updating Webform 7.x-4.1 to Webform-7.x-4.2. (Prior to the Webform update I updated Drupal from 7.32 to 7.34.)

"Warning: class_implements(): Class MailsystemDelegateMailSystem does not exist and could not be loaded in drupal_mail_system() (line 278 of /var/www/xxx/includes/mail.inc).
Exception: Class MailsystemDelegateMailSystem does not implement interface MailSystemInterface in drupal_mail_system() (line 283 of /var/www/xxx/includes/mail.inc)."

jfellers: you'll need to be using the 7.x-3.x-dev version of Mailsystem for now.

Thanks for very prompt response. Reverted back to webform-7.x-3.21.

Sending test form now results in:

"PDOException: SQLSTATE[HY000]: General error: 1364 Field 'serial' doesn't have a default value: INSERT INTO {webform_submissions} (nid, uid, is_draft, submitted, remote_addr) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4); Array ( [:db_insert_placeholder_0] => 12735 [:db_insert_placeholder_1] => 0 [:db_insert_placeholder_2] => 0 [:db_insert_placeholder_3] => 1416939192 [:db_insert_placeholder_4] => 10.147.89.95 ) in drupal_write_record() (line 7239 of /var/www/upgrade/includes/common.inc)."

That looks like a problem with reverting webform.

#2 works for me

#2 solves the problem

Issues people may be running into may be some sort of issue with the naming of files and how their system handles file names.

The originial file was MailSystemDelegateMailSystem. The new one is MailsystemDelegateMailSystem, which has one less capital S. Some filesystems, like Mac OS, disregard case changes and therefore Git or the filesystem might not detect the change. I ran the patch on a copy of the code from alpha1 that was upgraded to dev and then git recognized that I had changed the case of the file.
