AjaxProxy ExtraParams doesn't work
I have a combobox which fills it's data through an ASMX Web Service and I would like to pass an Extra Param (the country) in order to show only that country's cities. Country name must come from another Ext.NET control, a Cycle button's text. But the page cannot even load because it says it can't find the cycle button control. Following are the CycleButton's, the ComboBox's and the Web service's code.
This works:
Kind regards,

<ext:CycleButton MinWidth="197" Width="197" ID="MyCycleButton" runat="server" ShowText="true">
<Menu>
<ext:Menu runat="server" MaxHeight="200">
<Items>
</Items>
</ext:Menu>
</Menu>
<Listeners>
<Click Handler="MyApp.sampleFunction(this,e)" />
</Listeners>
</ext:CycleButton><ext:ComboBox

</ext:ComboBox>[WebMethod(EnableSession = true)]
public void GetCountryCities(string country)
{
HttpContext.Current.Response.ContentType = "application/json";
var requestParams = new StoreRequestParameters(HttpContext.Current);
int start = requestParams.Start;
int limit = requestParams.Limit;
string filter = !string.IsNullOrEmpty(requestParams.Query) ? requestParams.Query : "";
if (filter == "*")
filter = "";
Paging<City> resultCities = UserDataAccess.GetCountryCities(start, limit, filter, country);
HttpContext.Current.Response.Write(JSON.Serialize(resultCities));
}This works:
<ExtraParams>
<ext:Parameter Name="Country" Value="Greece" Mode="Value" />
</ExtraParams>Kind regards,
