100% test coverage, yet a bug. Can you spot it? Don't have too much confidence in 100% test coverage. For some reason the code below can return an old value for a field, even if the new value is read back from the DB.

gistfile1.cs

protected object GetValue(int fieldIndex, bool returnDefaultIfNull)
{
	if(_fields == null)
	{
		return null;
	}

	if(_fields.State == EntityState.Deleted)
	{
		throw new ORMEntityIsDeletedException("This entity is deleted from the database and can't be used in logic.", this);
	}

	var toReturn = _fields.GetCurrentValue(fieldIndex);
	var fieldInfo = _fields.GetFieldInfo(fieldIndex);
	if(_performsPersistenceLogic)
	{
		CheckForRefetch();
	}
	else
	{
		if((_fields.State == EntityState.OutOfSync) && !fieldInfo.IsPrimaryKey)
		{
			throw new ORMEntityOutOfSyncException("The entity is out of sync with its data in the database. Refetch this entity before using this in-memory instance.", this);
		}
	}

	// check if the field is set to a value, if that's required. 
	if(MakeInvalidFieldReadsFatal && (_isNew && !_fields.GetIsChanged(fieldIndex) && toReturn == null))
	{
		// not set to a value, illegal.
		throw new ORMInvalidFieldReadException(string.Format("The field '{0}' at index {1} isn't set to a value yet, so reading its value leads to invalid results. ", 
													fieldInfo.Name, fieldIndex));
	}

	object valueToReturn = null;
	bool cancel;
	OnGetValue(fieldIndex, out cancel);
	if(!cancel)
	{
		valueToReturn = toReturn;
	}
	bool authorizerResult = OnCanGetFieldValue(fieldIndex);
	if(!authorizerResult)
	{
		// not allowed. Set to null
		valueToReturn = null;
	}
	if((valueToReturn == null) && returnDefaultIfNull)
	{
		ITypeDefaultValue providerToUse = _typeDefaultValueProvider ?? CreateTypeDefaultValueProvider();
		if(providerToUse != null)
		{
			valueToReturn = providerToUse.DefaultValue(fieldInfo.DataType);
		}
	}
	OnGetValueComplete(fieldIndex);
	if(authorizerResult)
	{
		OnAuditEntityFieldGet(fieldIndex);
	}
	PostProcessValueToGet(fieldInfo, ref valueToReturn);
	return valueToReturn;
}
