I'm trying to send an email with an automated action from the hr.applicant model.

hr.applicant has the field 'email_from' defined in it.  I'm using the default email template 'Applicant: Acknowledgement' in my automated action, and this template uses the 'email_from' data to populate the 'To' address for the email.

The action is set to 'On Creation' for a trigger.

When a create a new Application record, the automated action is triggered, but the 'email_from' address contained in the Application is not inserted into the email, and it does not therefore get sent.

If I used the same template from the 'Send a message' button in the Chatter, the email is sent perfectly using the email address in the 'email_from' field.

It's just my automated action that isn't working.

Why isn't it working?  Do I need to get the context of the record somehow before sending the email?
