Sending custom email from Builtin Scripts throws GroovyCastException

[Matt Howell]

I would like to send a custom email from a workflow post function (using Script Runner), but first I have been using the "Builtin Scripts" in JIRA Administration to experiment.

When I preview various email configurations, the condition correctly evaluates to true, and the email is displayed correctly, but when I try to actually run the email, I get a GroovyCastException (details below). This seems to happen no matter what issue and/or settings I provide.

I've searched this site, as well as Google, and haven't come across a solution. Has anyone seen this, and been able to resolve it?

---

JIRA Version: 5.2.4
Script Runner Version: 2.1.3

Email Details:

• Condition: [issue.priority?.name == 'NA']
• Email Template: [Hello World]
• Subject Template: [Hello World]
• Email Format: [Plain Text]
• To Addresses: (my email address)
• Include Attachments: [None]
• From email address: (empty - shows proper email address in tooltip)
• Preview Issue Key: [DGS-128] (issue exists, and has priority properly set to NA)

Result:

org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'com.atlassian.jira.event.issue.IssueEvent@6181836a[issue=DGS-128,comment=<null>,worklog=<null>,changelog=[GenericEntity:ChangeGroup][id,16044][author,mhowell][created,2013-04-24 13:01:16.737][issue,12395],eventTypeId=1,sendMail=false,params={},subtasksUpdated=false]' with class 'java.lang.String' to class 'com.atlassian.jira.event.issue.IssueEvent'

Stack Trace:

Hi Matt, by any chance have you added the 'Send Custom Email' script under Installed Listeners (option under Script Listeners) ? If so, remove it and test the workflow post function again.

I got a similar Class cast error for the same script (Jira 4.1 & Script Runner 1.7.13), when testing (previewing) this built in script. I got this error everytime I specified a 'issue' object. But when I refreshed the script (cleared the entries & also removed it as added listener) & tried again with details (simple email text input data as yours!), it worked fine in workflow post function. I hope it helps.

I will look at that but you may not be able to actually run it from there... it's in the built-in scripts in the admin section just for previewing. If everything else works you should copy it to a workflow post-function.

I have also put the same configuration into a workflow post function. Although the issue progresses through the workflow correctly, an email never appears to get sent. I also don't see any errors in the catalina.out, or any emails show up in the Mail Queue.

Any suggestions on how to see more details of what might be happening?

[Matt Howell]

Quick update: I tried this again today as a post function, and no errors are logged in catalina.out. No email is sent, despite all other system emails working correctly. I am open to any further suggestions of how to triage this further?

Can you set the log level to debug and look for messages?
