AssertionError "You must specify a recipient e-mail address in the mail adapter"
This Error Reference applies to: Any version.
The error is occurring because PloneFormGen doesn't have a recipient address to which to mail the form input.
To fix this, choose the contents tab of your PFG form folder. Navigate to the "Mailer" item and use its edit tab. Choose the "addressing" fieldset and specify a recipient address.
If you don't see a content item titled "Mailer", look for a mail adapter with a different title. This message is generated by a mail adapter, so you must have one.By the way, if the recipient address isn't specified, PFG tries to use the e-mail address of the form folder's owner. So, you'll only see this error if you've failed to set an e-mail address in personal preferences.
