Hello Ralph,

Here is the script that i tried to customize according to my requirement, but no value is returned to the combo box.

Could you please suggest me if anything has gone wrong or i need to add something more..

dojo.provide("org.example.workitems.providers.TracksCountValueSet");
dojo.require("com.ibm.team.workitem.api.common.connectors.HttpConnectorParameters");

(function() {

dojo.declare("org.example.workitems.providers.TracksCountValueSet", null, {

    getFilteredValueSet: function(attributeId, workItem, context, filter) {

        var params= new com.ibm.team.workitem.api.common.connectors.HttpConnectorParameters();
        params.url= "https://localhost:9443/ccm/oslc/workitems/52/oslc_cm:tracksWorkItem";
        params.xpath= "//*[name()='oslc_cm:Collection']";
        params.useOAuth = true;
      

        var connector= context.getDataConnector("HttpConnector");
        var values= connector.get(params);

        var result= [];
        while(values.hasNext()){
            var entry= values.next();
             result.push(entry);
          
        }

        return result;
    }
});
})();

Thank you.

 I really thank you for the details. I tried it :)  however i could not customise to my requirement. I have posted it below...

could you please suggest me on that

I am sorry, but I don't have time to debug other people scripts. You can try to debug your scripts e.g. with the Chrome or Firefox development tools. First I would make sure that the values provided in the script work in the HTTP filtered value set.

PS: we recently found out that this will be very slow for large amount of input data as it has to be loaded several times.
