Subject: [Nant-users] bug in Element.cs?
> hi there,
>
> I'm trying to build a task that includes a [BuildElementCollection]
property

> [TaskName("foo")]
> class Foo {
> MyCollection col = null;
>
> [BuildElementCollection("bits", "bit")]
> public property MyBits {
> get { return col; }
> set { col = value; }
> }

> I think Element.cs has a bug on line 868. It's tries to set the property
> value onto the AttributeConfigurator instead of onto the element:
>
> // if value of property is null, create new instance of collection
> object collection = propertyInfo.GetValue(Element,
> BindingFlags.Default,
> null,
> null,
> CultureInfo.InvariantCulture);
> if (collection == null) {
> if (!propertyInfo.CanWrite) {
> throw new BuildException(string.Format(CultureInfo.InvariantCulture,
> "BuildElementArrayAttribute cannot be applied to read-only property
> with" +
> " uninitialized collection-based value '{0}' element for <{1} ...
> />.",
> buildElementArrayAttribute.Name, Name),
> Location);
> }
> object instance = Activator.CreateInstance(propertyInfo.PropertyType,
> BindingFlags.Public | BindingFlags.Instance,
> null,
> null,
> CultureInfo.InvariantCulture);
>
> // borked?
> propertyInfo.SetValue(this,
> instance,
> BindingFlags.Default,
> null,
> null,
> CultureInfo.InvariantCulture);
> }
>
> I think that last line should be:
>
> propertyInfo.SetValue(this.Element,
> instance,
> BindingFlags.Default,
> null,
> null,
> CultureInfo.InvariantCulture);
