How to get value of custom attribute of RTC WI .

So I was able to get this to work in a test project area.    Note that my STATE is different than yours, so you'll need to change that.  I tried to use the same attribute for Technical Lead as you did. 

Since you are making it a calculated value, RTC *assumes* that nobody else will change it other than the script, so that is why I get the owner and return the owner if it is not a defect or defect but not the right state.  If not, the if owner is set by someone else, it gets ignored.  I also did var's for everything so I could print things for debugging

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

(function() {
dojo.declare("org.example.CalculatedOwner", null, {
   
    getValue: function(attributeId, workItem, configuration) {
        var WorkItemAttributes = com.ibm.team.workitem.api.common.WorkItemAttributes;
        var wiType = workItem.getValue(WorkItemAttributes.TYPE);
        var wiState = workItem.getValue(WorkItemAttributes.STATE);
        var wiTechLead = workItem.getValue("com.wiley.workitem.attribute.assignedBA");
        var wiOwner = workItem.getValue(WorkItemAttributes.OWNER);

    if (wiType === "defect" && wiState === "com.ibm.team.workitem.defectWorkflow.state.s1" ) {
             return wiTechLead;
    } //type = defect
    else
        return wiOwner;
    }
});
})();

dojo.provide("org.example.CalculatedOwner");

dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

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

var CalculatedOwner= dojo.declare("org.example.CalculatedOwner", null, {

    getValue: function(attributeId, workItem, configuration) {
        console.log("Test");

if (workItem.getValue(WorkItemAttributes.TYPE) === "defect" && workItem.getValue(WorkItemAttributes.STATE) === "com.wiley.workitem.defectWorkflow.state.s1")

        return workItem.getValue(com.wiley.workitem.attribute.assignedBA);
    }
});
})();

Thanks a lot susan .. Appreciate your help .

BTW is it also possible to update the Subscriber list with the assignees Like as soon as owned by is Tech lead he should also get added to Subscriber list automatically .

Thanks
