	<Condition>
}
return newValues

Placeholders

Examples

The output of this snippet is a subset of the existing values of a multi-valued field which you could use in a Groovy expression, to

Send an email to all the customers watching the ticket using the Email issue post-function. For this, you need to add this script in the "Users from script" field in the post-function configuration
```
return issue.get("watches").findAll{
  it.isInProjectRole("Service Desk Customers",issue.get("project") )
}
```
