NHibernate.DataBinding.BindingList<T> couldn't sort on ActiveRecord using Nhibernate 1.2

Priority: blocker Milestone: Version 0.4.1
Component: NHibernate.DataBinding Version: latest

Description

NHibernate returns a PersistentGenericBag<T> witch doesn't inherit from List<T>. So the ConvertToList delegate in the BindingList<T> constructor won't work for 'return items as List<T>;' because items do not inherit from List<T>.

I solved it by modifying the Initialize function.

Error: Failed to load processor cs
No macro or processor named 'cs' found

None of the NHibernate collection types inherits from List<T>, only from IList<T>. Your proposed bugfix defeats the whole point of having a wrapper instance. If you create a new List<T> instance a lazy NHibernate collection will be initialized and as this happens during the initialization of the BindigList<T> there won't be any lazy collection functionality anymore.

I'll try to figure out if I can easily reimplement Sort() only relying on IList<T>.
