WordPress when sending a WP_Ajax_Response the response is not received.

Hi All,

I’m searching for days now for a solution to my problem.
When I send a WP_Ajax_Response the clientside is not receiving it.
I checked all possible tips on internet but still I can’t get it working.
Can somebody help me?

I registered the javascript file:

wp_register_script('test-ajax-js',get_template_directory_uri() . '/library/script/ajax.test.js',
                        array( 'jquery', 'wp-ajax-response' ), '1.0' );
                wp_enqueue_script( 'test-ajax-js');
		wp_localize_script( 'test-ajax-js', 'ajaxtest',
                        array(
                            'Ajax_Url' => admin_url( 'admin-ajax.php' ),
                            'deshopNonce' => wp_create_nonce( 'deshop-ajax-test-nonce' )
                        )
                );

This is the PHP code:

add_action('wp_ajax_shop_ajax_test', 'test_function');
add_action('wp_ajax_nopriv_shop_ajax_test', 'test_function');

function test_function() {
    check_ajax_referer( 'deshop-ajax-test-nonce' );

    $response = array( 'what'=>'validate_user_login',
                'action'=>'validate_user_login_results',
                'id'=>'1',
                'data'=>'OK'
                );

    $xmlResponse = new WP_Ajax_Response($response);
    $xmlResponse->send();

    exit();
}

and this is the javascript file:

jQuery(document).ready(function(event) {
    var post = {
                    action: 'shop_ajax_test',
                    _ajax_nonce: ajaxtest.deshopNonce
                };

    jQuery.post( ajaxtest.Ajax_Url, post, function(response){
                    var res = wpAjax.parseAjaxResponse(response, 'ajax-response');
                    jQuery.each( res.responses, function() {
                        var a = 0;
                    });
                });

});

While debugging the res content shows responses=[0]. In the jQuery.each function no responses are handled!

Thanks a lot for any tips that might help me out here!
