how to split a String into multiple String in a post-function?

[Riccardo Micozzi]

Hello there,

I have a CustomField(a label) where there is the possibility to insert more than a word(for example: apple, banana, watermelon) I need to write a Post Function, using the ScriptRunner in Jira Cloud) that get che Custom Field value and split the String into 3 different String(in the example on the top, one string for one fruit), obviously if in the CustomField there is only a word I will get only 1 String.

For the moment i have write this peace of code:

// get custom fields
def customFields = get("/rest/api/2/field")
.asObject(List)
.body
.findAll { (it as Map).custom } as List<Map>

def lista = customFields.find { it.name == 'Lista' }?.value

def lista1 = (issue.fields[lista] as String)?.replaceAll(/,.*/, ' ')

but Now I don't know how to move forward

P.S: I don't know if the peace of code that i have write is okay.

thanks to those who will answer
