Problem in using webservice in My ADF App

Question

hi ,OTN
I used this tutorial http://www.oracle.com/technetwork/testcontent/wsdc-085537.html to have a webservice in my ADF Application that returns Weather Application.I used Jdeveloper 11g 11.1.1.3.0. by follwing this tutorial I could get the weather Info.but the first time I run my page or the first time I press the button getWeatherBy Name after writing the place there is an error Mesage as follows
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Error occured when get webservices record ---> System.Data.SqlClient.SqlException: Procedure or function 'GetLatByPlace' expects parameter '@ZipcodeName', which was not supplied. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning() at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlDataReader.ConsumeMetaData() at System.Data.SqlClient.SqlDataReader.get_MetaData() at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior) at WeatherService.WeatherForecast.GetLatLonDataByPlaceName(String PlaceName) --- End of inner exception stack trace --- at WeatherService.WeatherForecast.GetLatLonDataByPlaceName(String PlaceName) at WeatherService.WeatherForecast.GetWeatherByPlaceName(String PlaceName) --- End of inner exception stack trac
when I press ok to this error Message.I could write the name of place and got Weather Info,so How can I prevent this error Message that appear every first Time the user call the page of Weather Forecast?
note : in the tutorial I noticed that it explained that there is an error Message will appear ( On the error window click OK. )

hi,frank
yes,the problem is that he asks about his parameter when the page is rendered for the first time,in the tutorial it prevents calling the web service before having
provided the place Name by making the refresh condition of the iterator #{adfFacesContext.initialRender} , although I did this the web Service is called,How I prevent calling it when i run my page ?
thanks shay,I will try it and tell the result
