first thanks a lot.
i use the Fiddler ,and the json information is:
Stations={"geometryType":"esriGeometryPoint","spatialReference":{"wkid":102100},"features":[{"geometry":{"x":13381735,"y":3702724,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"8"}},{"geometry":{"x":13384167,"y":3696158,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"1"}},{"geometry":{"x":13372653,"y":3698329,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"2"}},{"geometry":{"x":13372947,"y":3694618,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"9"}},{"geometry":{"x":13376655,"y":3685459,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"10"}},{"geometry":{"x":13383735,"y":3685039,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"3"}},{"geometry":{"x":13372207,"y":3699378,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"8"}},{"geometry":{"x":13371507,"y":3698318,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"9"}},{"geometry":{"x":13372947,"y":3694618,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"6"}},{"geometry":{"x":13374367,"y":3694538,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"10"}},{"geometry":{"x":13384887,"y":3703838,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"8"}},{"geometry":{"x":13384167,"y":3696158,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"5"}},{"geometry":{"x":13383907,"y":3683678,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"8"}},{"geometry":{"x":13382467,"y":3687998,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"4"}},{"geometry":{"x":13376607,"y":3690378,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"7"}},{"geometry":{"x":13374229,"y":3696227,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"11"}},{"geometry":{"x":13370729,"y":3691187,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"10"}},{"geometry":{"x":13375337,"y":3685363,"spatialReference":{"wkid":102100}},"attributes":{"FVALUE":"10"}}]}&f=json&
........
Especially ,in web application all is ok,
i guess the parameters i pass to the GP is not correct, and in json information the {"FVALUE":"10"}
is wrong, FVALUE should be integer type,here is string type???
can you show me a sample with how to pass the a lot of graphic with attribute to GP Service.
thanks very much!
