Custom attribute script error: TypeError: Cannot read property "common" from undefined

Troubleshooting


Problem

Customer is using a script-based condition for a read-only attribute:
dojo.provide("mycompany.team.workitem.condition.phase.readonly");
(function() {
	dojo.declare("mycompany.team.workitem.condition.phase.readonly", null, {
		matches: function(workItem, configuration) {
			var WorkItemAttributes = com.ibm.team.workitem.api.common.WorkItemAttributes;
			var WSTATE = workItem.getValue(WorkItemAttributes.STATE);
			if (WSTATE != undefined) {
				return true;
			}
		}
	});
})();

Symptom

The script works as expected (the attribute is modifiable on creation but not on any other state) but the following error is observed in the ccm.log
