Src/xWorks/RecordClerk.cs line 312 at r1 (raw file):

				if (decorator == null)
					break;
				da = decorator.BaseSda;

I think the RecordClerk is not the class that should actually be subscribing. The decorator that implements OnItemDataModified should actually be the one subscribed eliminating all this ugliness. May as well do that.

Code quote:

			var da = m_list.VirtualListPublisher;
			while (da != null)
			{
				if (da.GetType().GetMethod("OnItemDataModified") != null)
					ReflectionHelper.CallMethod(da, "OnItemDataModified", new [] {argument});
				var decorator = da as DomainDataByFlidDecoratorBase;
				if (decorator == null)
					break;
				da = decorator.BaseSda;
