How to populate a cascade field using Scriptrunner ?

[Jean-Christophe Gonzales]

Hello,

The context is to populate a field value entered in an Epicto all issues linked to it.

Though I am already using a Scriptrunner Custom Script Field to populate a field from another one, I need to do the same with a cascade fields, both the field read, and the field to be populated.

I don't know whether this is possible ?

I know how to read cascading custom field values, but I don't know how to feed that kind of field.

Thanks in adavance
