groovy script to send email failing in 5.2.2

[Brent Webster]

This groovy script(Script Runner 2.1.3) running in a workflow transition as a post-functions worked in Jira 4.3.6 to (1) cloned an issue from one project to another and then (2) sends out email to particular managers depending on the severity of the issue. Now that we have upgraded to 5.2.2, the cloning works but I see no emails. In the catalina.out, I see the following traceback:

I'm using the standard script runner template to create the email.  The condition is
    cfValues['Customer Severity']?.value == 'P1 - Network is down and business is impacted'

and the email template is

     ** URGENT **: P1 Customer Severity raised

     Summary: ${issue.summary}

     Account Name: <% out << cfValues['Account Name']?.value %>

     Contact: <% out << cfValues['Contact Name']?.value %>

     Severity: <% out << cfValues['Customer Severity']?.value %>

     Issue Number: $issue.key

     Description: ${issue.description}

     Raised by: <% out << issue.reporter?.fullName %>

     =========

Is there any conversion of the scripting templates that I missed?

You have to use issue.reporter?.displayName for your JIRA version.

You can use the official API documentation, here is a nice starting point: Atlassian API Reference

And you could take a look at the wonderful built-in scripts from Jamies Script Runner plugin to learn, how things work.

Thanks Henning, that did the trick. Where can I find documentation on these changes. Groovy scripting is a black art ;-) but it does the trick.
