Finding properties on interfaces which "inherites" other interfaces
-------------------------------------------------------------------

                 Key: IBATISNET-210
                 URL: https://issues.apache.org/jira/browse/IBATISNET-210
             Project: iBatis for .NET
          Issue Type: Bug
          Components: DataMapper
    Affects Versions: DataAccess 1.9, DataMapper 1.6
         Environment: Visual Studio 2005. .NET 2.0, Windows
            Reporter: Henrik Uffe Jensen


Here is the scenario explained. Don't know if this is really a bug or something 
that iBatis is just not supposed to support

First of all lets sketch some simple interfaces and domain classes

public interface IBaseDomain
{
    Guid Id { get; set; }
}

public interface IAddress : IBaseDomain
{
    string Streetname { get; set; }
}

public interface IUser : IBaseDomain
{
   IAddress Address { get; set; }
}

public class BaseDomain : IBaseDomain
{
    public Guid Id
    {
             get { ......... }
             set { ......... }
    }

}

public class Address : IBaseDomain, IAddress
{
    public string Streetname
    {
            get { ......... }
            set { ......... }
    }
}

public class User : IBaseDomain, IUser
{
    public IAddress Address
    {
        get { .......... }
        set { .......... }
    }

}

Then in a SqlMap we have some statements etc. and a resultmap based on the 
'User' class which uses 'Address.Id' and 'Address.Streetname' in the 
propertynames.... and then problems start because iBatis can only find 
'Streetname' property on IAddress and not property 'Id'. The reason is that 
'Id' exists in 'IBaseDomain' interface and not directly in the 'IAddress' 
interface.

In IBatisNet.Common.Utilities.Objects.ReflectionInfo and 
IBatisNet.Common.Utilities.Objects.Members.DelegatePropertyGetAccessor (only 
two places I got problems but maybe more exists) you will get en exception 
saying that "Property 'Id' on..... can not be found"

What I did to get going was to do some minor corrections in the mentioned 
classes where I check if type is an interface and in that case I don't only 
check for available properties on the type itself, but also use GetInterfaces() 
on the type to enumerate "inherited" interfaces and check for the property on 
these types.

I have found no sideeffects on these little hacks but I'm also only using a 
minor part of the framework
