I highly recommend Burke's approach since there's a lot of nuances that make a general solution will not work perfectly. There is also a high likelihood that if you haven't gotten e-mails or Error Handling to work that you are pretty new to vCO, so that website would be the BEST place to start! I'm sure they have examples of error handling and e-mails, but perhaps not e-mails for error handling...
With that said, I can try to help you along quickly... here are some quick and dirty steps to get something going... you may need the e-mail plugin installed... I'm not sure...
1. For all scripts or places where workflows can fail, bind the Exception variable to a string attribute of your choosing (I will call this ErrorText)
2. Link the exception workflow routes (instead of a normal blue color, link the red color) to a script. Make sure this script has access to ErrorText.
3. Inside the script, use the following (sloppily written) e-mail function:
function send_email(subject, body)
{
var message = new EmailMessage();
message.smtpHost = "xxxx.xxx.xxx.xxx";
message.fromName = "vCD Admin";
message.fromAddress = "vCD_Admin@example.com";
message.toAddress = emailReceivers();
message.subject = subject;
message.addMimePart(body,"text/html; charset=UTF-8");
System.log( "sending mail from:" + message.fromAddress + ", to:" + message.toAddress );
message.sendMessage();
}
send_email("Notice: Workflow Error",ErrorText);
