How to add a select cascade field value in a custom email [script runner postfunction]

Question

Hi Guys,

I'm following the documentation to send Send a custom email using a custom field https://scriptrunner.adaptavist.com/4.3.6/jira/builtin-scripts.html. It works, but with some problems.

The code

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

I'm using a select cascade field and the preview shows this.

Custom field : [null:JIRA SOFTWARE, 1:jira-users - Jira Users]

Why apperas the nulll and number 1?

Can I remove this values?

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.
