Hello,
We're having some problems with the proxies NHibernate generates.
All our mapped entities inherit from a generic class DomainEntity<T>:
Code:
public abstract class DomainEntity<T>
{
private T _id = default(T);
public virtual T Id
{
get { return _id; }
set { _id = value; }
}
public abstract String Label { get; }
/// <summary>
/// Equals
/// </summary>
/// <param name="other"></param>
/// <returns></returns>
public override bool Equals(object other)
{
if (this == other)
return true;
if (!GetType().Equals(other.GetType()))
return false;
DomainEntity<T> otherAsDomain = other as DomainEntity<T>;
if (otherAsDomain == null)
return false;
if (otherAsDomain.Id == null)
return false;
if (Id == null)
return false;
if ((Id.Equals(default(T))) || (otherAsDomain.Id.Equals(default(T))))
return false;
return _id.Equals(otherAsDomain.Id);
}
/// <summary>
/// GetHashCode
/// </summary>
/// <returns></returns>
public override int GetHashCode()
{
unchecked
{
int result;
result = Id.GetHashCode();
result = 29 * result;
return result;
}
}
}
We're getting some errors like this:
[ArgumentException: No se puede resolver el método Int32 GetHashCode() porque el tipo declarativo del identificador de método M2.Domain.DomainEntity`1[T] es genérico. Proporcione explícitamente el tipo declarativo a GetMethodFromHandle. ]

(The message says in spanish that the "Int32 GetHashCode()" cannot be resolved because the declaring type is generic, and that it should be resolved by passing the declarative type to GetMethodFromHandle).
