Andrei commented on NH-2317:
----------------------------

Hello,
I wanted to add that this issue breaks the functionality of the Expand method in a WCF Data Service scenario where paging is enabled. The WCF Data Service call first the paging operators (OrderBy, Skip, Take) and then does the projection for the Expand method.

> NHibernate.Hql.Ast.ANTLR.PolymorphicQuerySourceDetector.GetClassName(IASTNode querySource) en PolymorphicQuerySourceDetector.cs: line 62
