How to add a multi select (dropdown) custom field value to custom email [script runner postfunction]

[Bahar Dehkordi]

The below query doesn't seem to work when the custom field type is a select list (multiple choices) 

Custom field value: <% out << issue.getCustomFieldValue(com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("MySelect")) %>

Any idea how I can solve this? Thanks in advance!

Please try 

Custom field value: <% out << issue.getCustomFieldValue(com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("MySelect"))*.getValue().join(', ') %>

For a multiselect list getCustomFieldValue() returns a collection of Option object. With *.getValue() you convert this collection to a collection of the values of these Option objects. The value is the text the user sees. With join(', ') you convert this collection to one string, if there are multiple values these are separated by a comma.

Hello @Bahar Dehkordi

Try

Custom field value: <% out << issue.getCustomFieldValue(com.atlassian.jira.component.ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("MySelect")).toString() %>
