Sending custom email from Builtin Scripts throws GroovyCastException

Question

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=,worklog=,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: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'com.atlassian.jira.event.issue.IssueEvent@6181836a[issue=DGS-128,comment=,worklog=,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' at org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation.castToType(DefaultTypeTransformation.java:360) ...

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.

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

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?
