I am trying to experiment with the Stack Overflow API on my localhost and am struggling to get the authentication to complete. Here is my application JavaScript code (note that I am using IBM Worklight, hence the `wl` functions):

    function wlCommonInit(){
	
	// Common initialization code goes here
	SE.init({
		clientId: 4299,
		key: 'Dj9*ZH87BW6Q2hatei2mKw((',
		channelUrl: 'http://localhost:10080/',
		complete: function(data){
			console.log(data);
		}
	});
    }

    $('#submitButton').click(function(){
    SE.authenticate({
	success: function(data){
		var link='https://api.stackexchange.com/docs/answers#order=desc&sort=activity&filter=default&site=stackoverflow';
		$.getJSON(link+'?callback=?',function(json) {
			if(json.length!=0){
				console.log(json);
				$('h1').insert(json);
			}
		});
	
		
	},
	error: function(data){
		$('h1').insert("Authentication error");
	},
	scope: []
    });
    });

Essentially I am trying to return a JSON object using the `\answers` method.

I have set the OAUTH domain on the App page to `localhost`. When I deploy the app to the worklight development server and press the `#submitButton`, I get the following message:

> Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('http://localhost') does not match the recipient window's origin ('http://localhost:10080').

I have tried numerous potential fixes from discussion forums, but nothing seems to work.
