Unable to separate or remove duplicate elements from an array String or list

[J Manas Kumar]

Hi Everyone

I am trying to add fields from child custom field to parent custom field.

I am able to merge it, but i am not able to update parent issue custom field.

below i am first fetching child issue's field details, and then converting it into array.

sam ething i am doing for parent too.

i am able to merge it in 2 ways, but cant remove the duplicates using toUnique() or unique() method.

below i have the code.

any help will be appreciated.
