I wrote a calculated value script to read the value of subscribers and autopopulate a custom attribute (of type string).
The aim was to include the custom attribute in the query output.
(function() {
var WorkItemAttributes=;
dojo.declare("org.example.workitems.providers.CalculatedSubscribers", null, {
    getValue: function(attributeId, workItem, configuration) {
       return workItem.getValue(WorkItemAttributes.SUBSCRIPTIONS)
This script does not work. The custom attribute comes blank
-- Is the script correct? Is it possible to "getValues" of "subscriptions" like this?
-- Am I missing upon some steps here? I already included the "subscribedby" attribute as a "dependency" in the custom attribute.

Hi Monika,

you can find the valid attribute ID's for RTC here:

As you will notice there is no API WorkItemAttributes.SUBSCRIPTIONS which is basically because subscriptions are not at all managed as an attribute. It is not accessible in Java Script. Similarly inaccessible are approvals, work item links, attachments and the like.

Also see Lab 5 for what you can and can not do in scripts.

If you want to access the items mentioned above you need to use the JavaAPI and would probably have to create an Extension.
