Gantt Chart Not Refreshing After Adding New Item Using ODataV4Adaptor

Hello,

I've been facing an issue with my Gantt chart in the application. Specifically, the issue arises after I add a new item to the chart - the Gantt chart does not refresh automatically. I've noticed that the problem does not occur when editing existing items, only when adding new ones.

I'm using ODataV4Adaptor for handling data. Below is a sample POST request I send to the server:

--batch_9043fdce-793e-404b-8fd2-c37fe53ccaef
Content-Type: multipart/mixed; boundary=changeset_e49a9bfe-bc59-44bf-a1f3-d791cdce171c


--changeset_e49a9bfe-bc59-44bf-a1f3-d791cdce171c
Content-Type: application/http
Content-Transfer-Encoding: binary


POST EmployeeRoles HTTP/1.1
Accept: application/json, text/javascript, */*; q=0.01
Content-Id: 0
Content-Type: application/json; charset=utf-8


{"RoleId":"C01","StartDate":"2023-01-09T05:00:00.000Z","EndDate":"2023-01-11T21:00:00.000Z","Id":"2","EmployeeId":1}


--changeset_e49a9bfe-bc59-44bf-a1f3-d791cdce171c--
--batch_9043fdce-793e-404b-8fd2-c37fe53ccaef--

The server responds with:

{

    "responses": [
        {
            "id": "0",
            "atomicityGroup": "a9bab786-d48c-4c9b-a332-fb3cdb899e08",
            "status": 201,
            "headers": {
                "location": "https://******/odata/EmployeeRoles/$count?key=211",
                "content-type": "application/json; odata.metadata=minimal; odata.streaming=true; charset=utf-8",
                "odata-version": "4.0"
            },
            "body": {
                "@odata.context": "https://******/odata/$metadata#EmployeeRoles/$entity",
                "Id": 211,
                "StartDate": "2023-01-09T06:00:00+01:00",
                "EndDate": "2023-01-11T22:00:00+01:00",
                "EmployeeId": 1,
                "RoleId": "C01",
                "Name": ""
            }
        }
    ]
}

The response code is 201, which suggests that the new item has been successfully added to the database. However, despite this, the Gantt chart does not refresh automatically. There are no errors showing in the console that could help me understand what's happening.


Has anyone encountered a similar issue or can provide insight into what I could do to resolve this problem? Maybe I need to apply a refresh mechanism that I am currently unaware of?


Thank you in advance for any help!

Hello and welcome,

Unfortunately, I don't think the problem has been solved. After changing package.json line 26 to: "@syncfusion/ej2-angular-gantt": "^22.2.9", nothing changed in how gantt works. After adding a new row, still the gantt view is not updated with the new row. Please re-verify.

Ok, now we can say it's working, but I see that you've moved away from the batch approach to individual requests. Generally, I wouldn't have a problem with this, but I don't understand why you're sending an array with a single element instead of just one element?
