Creating a calculated field based on the number of labels?

[Jean-Francois Bouchard]

Hello,

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?

Thanks!

I'd use the script-runner add-on to populate the field with issue.getCustomFieldValue(cf).size()

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?

My formula:

<!-- @@Formula: ((issue.get("customfield_xxxx").size()).toString()) -->

I was able to manage null values.

Here is the formula:

<!-- @@Formula:
if (issue.get("customfield_xxxx")==null) return null;
return issue.get("customfield_xxxx").size(); -->
