Remove special characters from field returned from the parent issue

[Alex Cumberland]

JIRA Server 8.4.2   & scriptRunner 5.6.8.1

Creating a Custom scripted field in script runner 

Field Name : "Parent Labels"

script being used is :

      return (issue.parentObject != null) ? issue.parentObject.getLabels() : null;

Value it returns is when looking at subtasks in search is showing the list of labels from the parent ok.  Problem the labels are enclosed in brackets .

  For example :        [label_one, label_two, label_three]

Tried to use replaceAll but could not get that to work removing the "[" or "]" and would end up not returning anything.

Would like to be able to have it return as :    label_one, label_two, label_three

Hi @Alex Cumberland ,

Try this bit of code below.

def labels = issue.parentObject.getLabels()
labels.join(',')

Or

issue.parentObject.getLabels().join(',')
