Ok php json_encode return without [ ] on array length = 1

i solve this y mi php code

($response["total"] == 1)? $response["rows"][] = $list : $response["rows"] = $list;
     
        echo  json_encode($response);

Thx

the data is in that format, only copy so for compression. Filter work fine with more than one record but with one record ... the data are not loaded by the grid.

{"total":1,"rows":{"IDUsuario":58,"numeroDocumento":"19210473","FechaExpDocumento":"2014-04-30","primerNombre":"LUIS","segundoNombre":"ALBERTO","primerApellido":"BERNAL","segundoApellido":"PARADA","usuario":"aparada","password":"b214c5c3531225416d6a42b8a341234b77520cfe","fechaTrCr":"2014-05-28 15:22:55.000","usuarioTrCr":"ADMIN","fechaTrEd":"2014-05-29 09:40:26.000","usuarioTrEd":"ADMIN EDIT","idTipoDocumento":3,"RowNumber":"1"}}

  Thx, with the new version run ok.

Buy now, when my server script return more than one record everything is fine, the grid load the data perfectly, but when the server return one row the grid dont load the row data in the grid

The server json data is fine,

{
    "total": 1,
    "rows": {
        "IDUsuario": 58,
        "numeroDocumento": "19210473",
        "FechaExpDocumento": "2014-04-30",
        "primerNombre": "LUIS",
        "segundoNombre": "ALBERTO",
        "primerApellido": "BERNAL",
        "segundoApellido": "PARADA",
        "usuario": "aparada",
        "password": "b214c5c3531225416d6a42b8a341234b77520cfe",
        "fechaTrCr": "2014-05-28 15:22:55.000",
        "usuarioTrCr": "ADMIN",
        "fechaTrEd": "2014-05-29 09:40:26.000",
        "usuarioTrEd": "ADMIN EDIT",
        "idTipoDocumento": 3,
        "RowNumber": "1"
    }
}

I don't know why with only one record don't load the record in the grid after remote filter.
