JSON nested response not displaying

We are talking to an API and most of the calls are doing what we expect, but there's one set of calls I just get blank rows from and as many other clients can use it I must be doing something wrong

In my "controller.js" I have this

####
$http.get('/rest/queue/54').
    success(function(data, status, headers, config) {
      $scope.customers = data;
    }).
    error(function(data, status, headers, config) {
      // log error
    });
####

This is what I get returned when making the call from the command line:
####
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: application/json
Content-Length: 666
Date: Sun, 02 Nov 2014 15:18:40 GMT

{"shortName":"XYZX","clientName":"The Amazing One","queueSize":2,"queueDetails":[{"user":{"name":"Markus Sweden","email":"markus@sweden.com","phoneNumber":"46730773743","id":514,"activated":false,"pin":"6592","usersQueues":[]},"partySize":3,"timeEnteredQueue":1384497884000,"entryStatus":"NOTIFIED","estimatedWaitingTime":30,"userMessage":null,"id":97,"notes":""},{"user":{"name":"Miky","email":"Miky@hotmail.com","phoneNumber":"44785353533","id":8,"activated":false,"pin":"6363","usersQueues":[]},"partySize":7,"timeEnteredQueue":1384509850000,"entryStatus":"NOTIFIED","estimatedWaitingTime":65,"userMessage":null,"id":98,"notes":"Tall, striped jumper "}]}
####

And then on the webpage this:
####
<tr ng-repeat="customer in customers">
                      <td>{{customer.shortName}}</td>
                      <td>{{customer.queueDetails.user.name}}</td>
                </tr>
####

It's looping through and giving me back two rows as there's two entries, and if there's 12 I get 12 rows back but no data

I'm making a similar call which is working fine, that code below

Controller.js
####
$http.get('/rest/users/').
    success(function(data, status, headers, config) {
      $scope.customers = data;
    }).
    error(function(data, status, headers, config) {
      // log error
    });
####

This is what I get returned when making the call from the command line:
####
[{"name":"Thomas","email":"user@email.com","phoneNumber":"447901353380","id":2,"activated":false,"pin":"4340","usersQueues":[]},{"name":"Jim Ant","email":"jam@ial.co.uk","phoneNumber":"447868439992","id":4,"activated":false,"pin":"4397","usersQueues":[]}]
####

And then on the webpage this:
####
<tr ng-repeat="customer in customers">
                      <td>{{customer.name}}</td>
                      <td>{{customer.email}}</td>
                </tr>
####

This last one works just fine

It is me not using the right syntax when the JSON return is nested or something else I'm doing wrong ?
