Thymeleaf Array Element Join

Question

My Array is as follows:

members_array = [{'nickname':'mike','age':'21'},{'nickname':'dan','age':'30'}]

Objective is to join the nickname elements of the array.

${#strings.arrayJoin(members_array ,',')}

Result:

{nickname=mike,age=21},{nickname=dan,age30}

When in fact what i really want is just

mike, dan

Any help would be appreciated. Thanks

Use Collection Projection for this.

${#strings.arrayJoin(members_array.![nickname], ',')}
