I am trying to create a calculated field that gives us the number of labels (from a custom label-type field) attached to the very same issue, but I am starting to doubt the possibility of it.
Any ideas of how I could go about it?
I am using a calculated field to get the number of Labels, but if the value of custom field is null, it throws me an error "Target exception: java.lang.NullPointerException: Attempt to invoke method size on null value"
How do i overcome this error?
<!-- @@Formula: ((issue.get("customfield_xxxx").size()).toString()) -->
