Cannot call method "getDataConnector" error

Hi David, Thanks for responding. I was invoking the getFilteredValueSet method from another class. I'm trying to find a way to return a calculated value and still use the HttpConnector. See code sample below.

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

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

dojo.declare("myclass",null,{
               
        getFilteredValueSet: function(attributeId, workItem, context, filter) {
           
            var params= new HttpConnectorParameters();
            params.url= myURL;
            params.xpath= "//srnumber";
            params.columnXpaths= ["./nextnumber/@data"];
            params.columnIds= ["nextnumber"];
           
            var connector= context.getDataConnector("HttpConnector");
            var values= connector.get(params);
           
            var result= [];
            var srnumber = "";
            while(values.hasNext()){
                var entry= values.next();
                var nextsrnumber= entry.getById("nextnumber");
                if (nextsrnumber.indexOf(filter) > -1) {
                    result.push(nextsrnumber);
                    srnumber = nextsrnumber;
                }
            }
                 
              return srnumber;
        }     
       
       
});

dojo.declare("org.example.workitems.providers.CalculatedValueSkeleton", myclass, {

    constructor: function(attributeId, workItem, context, filter) {
   
            var srnvalue = new myclass();
            this.srnumber = srnvalue.getFilteredValueSet();
        },
       
    getValue: function(attributeId, workItem, configuration) {
       
        return this.srnumber;
       
    }
});
})();

Hi Alicia,
are you able to get Connector Object, i am still getting "getDataConnector" error".

Please help.
