Attribute Customisation: Setting a Custom Attribute (enumerated) using a Calculated Value script

We have added a custom attribute ("Risk RAG") to the Risk work item. The attributed is an enumerated type with possible values of "Red", "Amber" and "Green". We are attempting to set the value using a script which utilizes the "Exposure" attribute. Here is the script code:
(function() {
    dojo.declare("risk.rag.ValueProvider", null, {
        getValue: function(attribute, workItem, configuration) {
            var riskrag = "Unassigned";
            var exposure = 0;
            var redrag = 59;
            var amberrag = 17
            var greenrag = 1
            var exposure = workItem.getValue("");
            if (exposure > redrag) {
                riskrag = "Red";
            } else {
                if(exposure > amberrag){
                    riskrag = "Amber";
                } else {
                    riskrag = "Green";
            return riskrag;
When the attribute is displayed in the work item editor and error ("The selected value is not applicable") is displayed next to the attribute. I suspect that this is due the fact we have not assigned the enumerated literal correctly.
Please can you advise on how I retrieve and set the enumerated literal within the Calculated Value script.

Many thanks

what are the ID's of your enum values?  ID's are what u need to manipulate.

I don't know how to retrieve the enum value IDs via javascript.

 Hello Ian,
you're correct. You should not use enum values labels (Red, Amber, ...)
but fully qualified id's (, etc...)

To map id to label, check Project Area Source.

Hope it helps.

Eric, many thanks for the pointer. Once I have the Id's how do I return the correct value?

sam detweiler commented May 16 '14, 9:23 a.m.

how does he get the enum shape? literal id ='text string' so that his code is not dependent on the last time he manually read the process config source.

sam detweiler commented May 16 '14, 9:31 a.m.

you return the id string (for example) ''

ic= your initials
