Hi
Typical server response on create looks like this :
{
"id": "row_1",
"error": "",
"fieldErrors": [],
"data": [],
"row": {
"DT_RowId": "row_1",
"item": ".kh",
"done": "0",
"priority": "2"
}
}

When should we populate the "data" field in server response ? In which case can I used it ?

Regards Mirek
