Hey Lev,

In my testing of the new 7.x-1.x-dev branch, I've been able to successfully subscribe users to Mailchimp from the user registration form. I've also been able to successfully merge fields including the username, user id, and user e-mail address. So that's the good news... :-)

But upon successful registration, I'm also getting the following warning messages on the registration confirmation page:

Warning: array_merge(): Argument #1 is not an array in _form_set_class() (line 3490 of /Users/benkaplan/git/drupal/includes/form.inc).
Warning: array_flip(): Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 167 of /Users/benkaplan/git/drupal/includes/entity.inc).
Notice: Array to string conversion in mailchimp_mailchimp_merge_values() (line 762 of /Users/benkaplan/git/drupal/sites/all/modules/mailchimp/mailchimp.module).
Notice: Array to string conversion in mailchimp_mailchimp_merge_values() (line 762 of /Users/benkaplan/git/drupal/sites/all/modules/mailchimp/mailchimp.module).
Notice: Array to string conversion in mailchimp_mailchimp_merge_values() (line 762 of /Users/benkaplan/git/drupal/sites/all/modules/mailchimp/mailchimp.module).

Since I'm merging three variables in my testing (and there are three line 762 notices), the line 762 warning is probably related to all merge variables regardless of which merge variables they are.

Any ideas on how to fix?

Thanks,
Ben

not sure if there is a common module, between your setup and mine ? and im using d7-dev from 25th August, also noticed when cron runs manually, the error appears twice, but on page refresh it clears from the cron run page, but still shows consistently on the node display.

Im narrowing down, new content nodes of the same content type are ok, so suspect the node, will report back if once i work out what is happening. Have upgraded to new entity-dev, still no joy.

Ok, think the upgrade to entity dev may have sold my problem, I had to delete the node, and recreate but the error has no gone, hooray, onto the next thing, hope this helps in some way.

I've found this same error, and I'm not using MailChimp, so this is not a module issue. I just found it with form_set_error in the actions page of a clean (no modules) D7 install.

Not sure, but mailchimp.module:245 is

      $account = user_load(array('uid' => $form_state['values']['uid']));

The signature for user_load in D7 has changed forn D6 ( http://api.drupal.org/api/function/user_load/7 ) and user_load now should be called with "$uid Integer specifying the user ID to load.".

If you can try to make that change manually and try if the error persist, that might help to fix this issue.

Edited: line should be:

      $account = user_load($form_state['values']['uid']);
