SelectBox and JSON reader -- SelectBox only shows "Loading...."

in my form I have a SelectBox, which should load the data from the server.
When I click on the "down" arrow of the SelectBox, it only displays "loading..." and no content is shown.

here is my SelectBox:

Code:

---

<ext:SelectBox ID="ContractGroup" runat="server" DisplayField="ContractGroupName"
            ValueField="ContractGroupID" EmptyText="ContractGroup...">
            <Store>
                <ext:Store ID="Store_ContractGroup" runat="server">
                    <Model>
                        <ext:Model ID="Model1" runat="server">
                            <Fields>
                                <ext:ModelField Name="ContractGroupID" />
                                <ext:ModelField Name="ContractGroupName" />
                            </Fields>
                            <Proxy>
                                <ext:JsonPProxy Url="/Contract/GetContractGroup">
                                    <Reader>
                                        <ext:JsonReader AutoDataBind="true">
                                        </ext:JsonReader>
                                    </Reader>
                                </ext:JsonPProxy>
                            </Proxy>
                        </ext:Model>
                    </Model>
                </ext:Store>
            </Store>
        </ext:SelectBox>

---

and here is the json response form the server:

Quote:

---

[{"ContractGroupID":1,"ContractGroupName":"root"},{ "ContractGroupID":2,"ContractGroupName":"MasterGro up"}]

---

I did search the web already for an example, where I could see what I am doing wrong, but I could not find anything.

I solved it by changing the JsonPProxy to AjaxProxy

thanks
