Linq-ing Calculated Properties

[Azar Gurbanov]

Hi all,

does anyone have experience implementing this: https://hendryluk.wordpress.com/2011/09/06/nhibernate-linq-ing-calculated-properties/

I cannot get it working.  Throws the following exception when the query is executed: 

NHibernate.Hql.Ast.ANTLR.InvalidPathException: Invalid path ‘x.Weight’

One workaround I found was to replace the linq parameter name, so the following query from the example:

from parcel in Session.Query<Parcel> where parcel.Fee > 1000 select parcel;




would become:

from x in Session.Query<Parcel> where x.Fee > 1000 select x;

I'm suddenly encountering this problem, whereas I'm sure I had this working earlier!  Has anyone made progress on it?

I solved the InvalidPathException problem here: https://stackoverflow.com/questions/65288396/how-do-i-get-nhibernate-to-generate-sql-for-a-computed-property/65302675#65302675
