I hope this helps you . I'm guessing it relates to the animation and excessive repaint calls. Try using tabs.setAnimateTabSelection(false).

        BufferedReader reader = new BufferedReader(new InputStreamReader(json));
        StringBuilder sb = new StringBuilder();
        String line = reader.readLine();
        while (line != null) {
            sb.append(line);
            line = reader.readLine();
        }
        reader.close();
        JSONArray jsonReply = new JSONArray(sb.toString()); 

        System.out.println("length is"+jsonReply.length());
        ArrayList<String> id=new ArrayList<String>();
        for (int i = 0; i < jsonReply.length(); i++) {

like below fixes the issue First of all you should fix the JSON data:
replace "parent": "" to "parent": "null" in the root element you should invert the values of isLeaf property: change all true values to false and change all false values to true you should remove "cell" part from all items The value "records": 1 don't corresponds 4 items of data. I suppose that the correct value should be "records": 4, but the best will be to remove the pager from the list of options of the grid. In the case setting of any page, total or records will be not important.
code :
[
    {
        "id": "1",
        "name": "ECHANGEUR",
        "level": "0",
        "parent": "null",
        "isLeaf": false,
        "expanded": false,
        "loaded": true
    },
    {
        "id": "1_1",
        "name": "Intervention Aller sur Site",
        "level": "1",
        "parent": "1",
        "isLeaf": false,
        "expanded": false,
        "loaded": true
    },
    {
        "id": "1_1_1",
        "name": "Date et heure d'arrivée sur le site",
        "level": "2",
        "parent": "1_1",
        "isLeaf": true,
        "expanded": true,
        "loaded": true
    },
    {
        "id": "1_1_2",
        "name": "Consignation de l'échangeur",
        "level": "2",
        "parent": "1_1",
        "isLeaf": true,
        "expanded": true,
        "loaded": true
    }
]
$("#grid").jqGrid({
    url: "user2132268.json",
    datatype: "json",
    colNames: [ 'id', 'Prestations'],
    colModel: [
        {name: 'id', width: 100, key: true, hidden: true},
        {name: 'name', width: 785, sortable: false}
    ],
    sortname: 'id',
    sortorder: "asc",
    hiddengrid: true,
    gridview: true,
    treeGrid: true,
    treeGridModel: "adjacency",
    ExpandColumn: 'name',
    ExpandColClick: true,
    jsonReader: { repeatitems: false, root: function (obj) { return obj; } },
    height: "auto"
});

With these it helps I tried to make HTTP Post to a web service and I got a message. Now, I'm trying to parse it using JSON. All I want to do is showing the message in listview after parsing it. However I'm constantly getting a null pointer exception in this line : " list.setAdapter(numberAdapter); " . I couln't find why it occurs. Can anyone help me? Thank you in advance. , You are missing setContetnView
code :
 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); //missing  
        ListView list = (ListView) findViewById(R.id.listView);
Parsing JSON with jmeter to pass a json array as it is from previous HTTP response to a new HTTP Request

Hope that helps I would recommend using JSR223 PostProcessor instead of this JSON Path one.
Add JSR223 PostProcessor as a child of the request which returns above JSON Choose groovy in the "Language" dropdown
code :
import groovy.json.JsonOutput
import groovy.json.JsonSlurper

def jsonSlurper = new JsonSlurper();
def response = jsonSlurper.parseText(prev.getResponseDataAsString());
def json = JsonOutput.toJson(response.details[0].outBound[0]);

vars.put("json", json);
Does anyone know the best way for components in Angular to share datas?

Does that help I really like Angular, but one of it's weaknesses is communicating between two non-related components in my opinion. If they are child parent its pretty easy, but otherwise you need to use a service and a subject.
code :
@Injectable()
export class SearchingService {
    private subject = new Subject<any>();

    submitSearch(message: string) {
        this.subject.next({ text: query});
    }

    clearSearch() {
        this.subject.next();
    }

    getSearch(): Observable<any> {
        return this.subject.asObservable();
    }
}
