How to make autofill insight field whichdepends from the another insight field?

[Ihor Krapivin]

In my case, I need that one insight field to autofill when another insight field has an option. How I can do it? I've already tried scripts from this page https://confluence.atlassian.com/servicemanagementserver0420/post-functions-1095772164.html 
it doesn't work
and tried IQL expressions - it also doesn't work.
Can someone help me?)

I think that you can use the behavior script.

def fieldChanged = getFieldChanged()
def checkedField = getFieldById("checked_field_id")

if (fieldChange.getFieldId()== "checked_field_id"){
    def fieldNeedToFillValue = getFieldById("field_need_to_fill_id")
    //Perform your business logic here, example
    fieldNeedToFillValue.setFormValue(fieldChange.getValue())
}

Hope it can help you
