extendModel not being used for get route

[emadd]

Anything obviously wrong here?

My object factory...

(function() {
    'use strict';
    var module = angular.module('common.model.domain', []);
    module.factory('Domain', function() {

        var Domain = function(data) {

            //DEFAULT PROPERTIES
            this.domainId = 0;
            this.less = null;
            this.css = null;

            //EXTEND THIS OBJECT WITH CONSTRUCTOR DATA
            if(data && angular.isObject(this)){
                angular.extend(this, data);
            }

            //CUSTOM METHODS
            this.lessObj = function(){
                if(this.less === null){
                    return null;
                }else{
                    return JSON.parse(this.less);
                }
            };
        };
        return Domain;
    });
})();

Within my service...

var rDomains = Restangular.withConfig(function(config){
    config.setRestangularFields({
        id: 'domainId'
    });
});

rDomains.extendModel('config/domain', function(data){
    return new Domain(data);
});

var domains = Domains.all('config/domain');

DomainService.getList = function() {
    return domains.getList().then(function(results){
        return results;
    }, function(err){
        console.log('DomainService.getList error',err);
    });
};

DomainService.get = function(id) {
    return domains.one(id.toString()).get().then(function(result){
        return result;
    }, function(err){
        console.log('DomainService.get error',err);
    });
};

Use of service...

//fetching a list of objects uses extendModel
DomainSvc.getList().then(function(domains){
        return domains;
});

//fetching one does not use extendModal
DomainSvc.get($stateParams.itemIds).then(function(d){
         return d;
});

This looks like you might have a bug in the way you've set up the multiple factories. Can you please post a working Plunkr example?
