I have a json data returns from php like this:

        },
        {
            "sender": "btknctTR",
            "message": "This i second test message",
            "date": "Jun 11, 2016 1:48:54 PM"
        }
    ]
},
{
    "id": 198,
    "sender": "btknctTR",
    "title": "Yeni yeni yeniden",
    "date": "Jun 11, 2016 12:53:32 PM",

        },
        {
            "sender": "DonduranAtes",
            "message": "asdasd\r\n",
            "date": "Jun 11, 2016 7:54:50 PM"
        },
        {
            "sender": "btknctTR",
            "message": "sadasdasdasd",
            "date": "Jun 11, 2016 7:55:14 PM"
        }
    ]
},
{
    "id": 3810,
    "sender": "btkncttr",
    "title": "asdasdasdasdas",
    "date": "Aug 6, 2016 10:55:36 AM",
    "lastupdatedate": "Aug 7, 2016 10:33:19 PM",
    "category": "Diger",
    "priority": "Normal",
    "appointedRole": "Moderatör",
    "archived": true,
    "messages": [
        {
            "sender": "btkncttr",
            "message": "This is the message",
            "date": "Aug 6, 2016 10:57:07 AM"
        },
        {
            "sender": "player",
            "message": "This is the message tooo",
            "date": "Aug 6, 2016 10:57:07 AM"
        }
    ]
}
]

But I can't find how can ng-repeat theese. When I wrote {{data.sender}} returns error [ngRepeat:dupes] in console.

I need list this values in ticket-list page, this is a support system for users.

You are getting [ngRepeat:dupes] error in console because there are some duplicates in the data.

If you want to loop through all the data and show sender, You can do something like this

<div ng-repeat="data in jsonData track by $index">{{data.sender}}</div>

$index keeps track of each object in the array using index of the object in the array.
