Smart value for Cascading fields

[Basavaraj Bhuti]

I need to send mail by automation, That mail should contain the values of the cascade field values. I have used the following smart value but its not able to get field values 

{{issue.parent.value}}

Here the parent is name of the field.

how to achieve the requirement..?

To get a value from a single pick list use {{issue."customfield_1057".value}}, for a cascading list {{issue."customfield_1057".child.value}}

"customfield_1057"= sample custom field
