[nhibernate-issues] [NHJIRA] Commented: (NH-2328) Linq query on <Any/> fails

[Andrei A. (JIRA) <nh...@gm...>]

    [ http://216.121.112.228/browse/NH-2328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=21154#action_21154 ] 

Andrei Alecu commented on NH-2328:
----------------------------------

More information:

Using an explicit parameter works:

	var boxes = s.CreateQuery("from ToyBox t where t.Shape.class = :clazz")
                    .SetParameter("clazz", typeof(Square).FullName).List<ToyBox>();

Upon further inspection, it works because the implementation calls NullSafeSet() on MetaType while setting the parameter. If the type is specified inline, NullSafeSet isn't called.

I believe the proper fix here would be for the query parser to extract what's after = here and pass it in as a parameter, if possible, so that NullSafeSet() is called.
