Hi,
I'm trying to define dynamic generic type definition, inherited from
another generic type definition (something like class B<T> : A<T>).
I'm using similar code to set base type (if this is wrong, all other
problems will be probably gone):

void SetBaseType(TypeBuilder builder, Type sourceType)
{
    Type[] ga = sourceType.GetGenericArguments();
    string[] gaNames = new string[ga.Length];

    for (int i = 0; i < ga.Length; i++)
        gaNames[i] = ga[i].Name;

    GenericTypeParameterBuilder[] gaBuilders =
typeBuilder.DefineGenericParameters(gaNames);
    // Setting constraints is here

    Type baseType = sourceType.MakeGenericType(gaBuilders);
    typeBuilder.SetParent(baseType);
}

Now, this works until i want to override any method. When I'm using
sourceType to get method that will be overridden, builder.CreateType()
throws this exception "System.TypeLoadException":
Type 'Foo.ListEx`1' from assembly 'Boo, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=null' tried to override method
'GetObjectData' but does not implement or inherit that method.

(Note: I'm sure that IL code generation is fine)
I think that problem is that sourceType isn't actually new type parent,
however when any GetMethod (or similar) method on builder.BaseType fails
with exception "System.NotSupportedException: Specified method is not
supported." until type is created (thats probably because i used
non-built types as generic arguments).

Problem is that i'm stuck in the loop.. i can't get methods that should
be overriden until type is created, and can't override methods after
type is created :)
Any ideas?

Thanks
