Hello,

I am a little bit distressed. I have generated a WebService to handle my database access from a desktop and mobile device application. Everything works fine. But for now I get a "NullReference" exception, but only on my mobile device:

System.NullReferenceException wurde nicht behandelt. Message="NullReferenceException" StackTrace: bei SD.LLBLGen.Pro.ORMSupportClasses.EntityBase2.Xml2Entity() bei SD.LLBLGen.Pro.ORMSupportClasses.EntityBase2.ReadXml() bei SD.LLBLGen.Pro.ORMSupportClasses.EntityBase2.ReadXml() bei System.Xml.Serialization.XmlSerializationReader.DeserializeSerializableElement() bei System.Xml.Serialization.XmlSerializationReader.deserializeElement() bei System.Xml.Serialization.XmlSerializationReader.DeserializeElementMember() bei System.Xml.Serialization.XmlSerializationReader.deserializeMembers() bei System.Xml.Serialization.XmlSerializationReader.DeserializeComplexElement() bei System.Xml.Serialization.XmlSerializationReader.deserializeElement() bei System.Xml.Serialization.XmlSerializationReader.DeserializeElementMember() bei System.Xml.Serialization.XmlSerializationReader.deserializeMembers() bei System.Web.Services.Protocols.SoapMessageParser.execute() bei System.Web.Services.Protocols.SoapMessageSerializer.Deserialize() bei System.Web.Services.Protocols.SoapHttpClientProtocol.doInvoke() bei System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke() bei MobileOffice.Web.Service.GetCurrentMandator() bei MobileOffice.BL.Generic.get_Mandant() bei MobileOffice.UI.Leistungserfassung.Zusatzleistung.InitEntity() bei MobileOffice.UI.Leistungserfassung.Zusatzleistung.cboLeistung_KeyPress()

here is the generated and (modified ) code from the reference.cs:

        [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/GetCurrentMandator", RequestNamespace="http://tempuri.org/", ResponseNamespace="http://tempuri.org/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
        public MandantenstammEntity GetCurrentMandator() {
            object[] results = this.Invoke("GetCurrentMandator", new object[0]);
            return ((MandantenstammEntity)(results[0]));
        }
        
        /// <remarks/>
        public System.IAsyncResult BeginGetCurrentMandator(System.AsyncCallback callback, object asyncState) {
            return this.BeginInvoke("GetCurrentMandator", new object[0], callback, asyncState);
        }
        
        /// <remarks/>
        public MandantenstammEntity EndGetCurrentMandator(System.IAsyncResult asyncResult) {
            object[] results = this.EndInvoke(asyncResult);
            return ((MandantenstammEntity)(results[0]));
        }

Last week it was still working

Please state: llblgen pro version, build date of runtime libs etc.

LLBLGen Pro. Version 1.0.2005.1 Final (February 9th, 2006) SD.LLBLGen.Pro.ORMSupportClasses.CF11.dll (1.0.2005.1, 11.02.2006)

Regards, Carlo

Could you try with the latest runtime library builds for 1.0.2005.1 please?

It´s the same behaviour. Any other suggestions?

This happens on CF.NET 1.0? What has changed since the last time it did work?

I´m using CF 2.0. I´ve changed nothing (as far as I know )

Research to be continued ...

I have found the problem:

The generated DAL-Code was out of sync (DAL Desktop/DAL PPC) I´m not sure wich devil has generated the code only for the desktop (maybe me, myself and I )
