I am trying to "save" Pland for history using Tags.

I am trying to add tag for every "Planed for" value using attribute customisation -> Script base Value set.

my script is:

dojo.provide("org.myorg.CopyPlanForToTag");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

(function() {
var WorkItemAttributes= com.ibm.team.workitem.api.common.WorkItemAttributes;
var MyTags= [];

dojo.declare("org.orbotech.CopyPlanForToTag", null, {

    getValue: function(attributeId, workItem, configuration) {
       MyTags.push(workItem.getValue(WorkItemAttributes.PLANNED_FOR));
  return MyTags;

    }
});
})();

I set the Tag to use the script & add Planed for as dependencies.

I dont get any value in the Tag.

can I set the Tag this way?

is there another way do add tag?

thank you
