[web service parameters problem]

hi guys,

I have a problem invocating a webservice that has 4 different parameters.

this is what I do.

1) File New Chart Type

2) use web services and select my webservice and method

3) then I set my parameters and everything crashes...

 

System.NullReferenceException: Object reference not set to an instance of an object. in PowerGadgets.Data.WebServiceSource.a(ParameterInfo A_0, Boolean A_1) in PowerGadgets.Data.a.a() in PowerGadgets.Data.a.a(Object A_0, EventArgs A_1) in System.Windows.Forms.ComboBox.OnSelectedIndexChanged(EventArgs e) in System.Windows.Forms.ComboBox.WmReflectCommand(Message& m) in System.Windows.Forms.ComboBox.WndProc(Message& m) in System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) in System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) in System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

 

is there anything that u know is not working using webservices as source of data???

lemme know
