Hi,

The folowing code is not valid because DispatchListEntity.PrefetchPathDispatch appears 2 times.

IPrefetchPath prefetch = new PrefetchPath((int)EntityType.DispatchListEntity);

            prefetch.Add(DispatchListEntity.PrefetchPathDispatch).SubPath.Add( DispatchEntity.PrefetchPathAddressDestination).SubPath.Add( AddressEntity.PrefetchPathZipCode).SubPath.Add( ZipCodeEntity.PrefetchPathAreaDefinition).SubPath.Add(AreaDefinitionEntity.PrefetchPathRegion);
            prefetch.Add(DispatchListEntity.PrefetchPathDispatch).SubPath.Add( DispatchEntity.PrefetchPathAddressPickup).SubPath.Add( AddressEntity.PrefetchPathZipCode).SubPath.Add( ZipCodeEntity.PrefetchPathAreaDefinition).SubPath.Add( AreaDefinitionEntity.PrefetchPathRegion);

How do I get it right?

Use a prefetchPathElement as follows:

            PrefetchPathElement2 prefetchDispatch = DispatchListEntity.PrefetchPathDispatch;

            prefetchDispatch.SubPath.Add(DispatchEntity.PrefetchPathAddressDestination).SubPath.Add( AddressEntity.PrefetchPathZipCode).SubPath.Add( ZipCodeEntity.PrefetchPathAreaDefinition).SubPath.Add( AreaDefinitionEntity.PrefetchPathRegion);
            prefetchDispatch.SubPath.Add(DispatchEntity.PrefetchPathAddressPickup).SubPath.Add( AddressEntity.PrefetchPathZipCode).SubPath.Add( ZipCodeEntity.PrefetchPathAreaDefinition).SubPath.Add( AreaDefinitionEntity.PrefetchPathRegion);

            IPrefetchPath prefetch = new PrefetchPath((int)EntityType.DispatchListEntity);
            prefetch.Add(prefetchDispatch);

This:

PrefetchPathElement2 prefetchDispatch = DispatchListEntity.PrefetchPathDispatch;

returns the folowing error:

Cannot implicitly convert type 'SD.LLBLGen.Pro.ORMSupportClasses.IPrefetchPathElement' to 'SD.LLBLGen.Pro.ORMSupportClasses.PrefetchPathElement2'. An explicit conversion exists (are you missing a cast?)

If I try this:

PrefetchPathElement2 prefetchDispatch = (PrefetchPathElement2)DispatchListEntity.PrefetchPathDispatch;

Then this line:

prefetchDispatch.SubPath.Add(DispatchEntity.PrefetchPathAddressDestination).SubPath.Add( AddressEntity.PrefetchPathZipCode).SubPath.Add(ZipCodeEntity.PrefetchPathAreaDefinition).SubPath.Add( AreaDefinitionEntity.PrefetchPathRegion);

returns:

The best overloaded method match for 'SD.LLBLGen.Pro.ORMSupportClasses.IPrefetchPath2.Add(SD.LLBLGen.Pro.ORMSupportClasses.IPrefetchPathElement2)' has some invalid arguments

Oh sorry, just remove the '2' from the end of the class name. IPrefetchPathElement2 is used in the Adapter model.

So if you are using the SelfServicing model then the following should be correct:

PrefetchPathElement prefetchDispatch = DispatchListEntity.PrefetchPathDispatch;
