Automation - Check if previous value is blank

[Andy McCormick]

It's quite simple to check if the current value of a field is blank. However, I'm trying to run automation only if the value was previously not empty. In this case the Due Date.  Am I missing something obvious? 

In the Issues Field Condition, you can only select the field as it currently is after the change. I tried using JQL with `{{fieldChange.from}} != ""` and `{{fieldChange.fromString}} != ""` which both resulted in errors.

Hi Randy,

The components field is an array so to set the value you require, you should use syntax similar to the example show below where you specify the component by its name using a name, value pair.

issueInput.fields.components = [[name: '<ComponentNameHere>']]

That did it.  Thanks!

Any idea how you do this so that you can add a new component without overwriting any components that are already there? I have a use case where I want to be able to add multiple components either through scripts or by the users.

@E01807  you can read from the components field, add to the array, then set the array to the issueInput component field as Kristian showed above.

Thanks @Randy . I'm pretty new to this. Would it be possible for you to post a code snippet on how this might be achieved?

[Randy]

This might work.  Note that it's untested.  Assumes Issue and issueInput are available in the script context as bindings

def newComponentList = issue.fields.components.clone()

newComponentList.add([name: 'New Component'])

issueInput.fields.components = newComponentList
