Using the current aplha, I have a named query with the named parameter :task_list in an IN clause.

Nhibernate throws an exception:
NHibernate.QueryException: No type assigned to parameter 'p0': be sure to set types for named parameters.

p0 is :task_list

Nhibernate determines from the first element of the collection passed that it is a string later on; but at the time the parameter is passed using SetParameterList the NHibernate.SqlCommand.Parameter object for the parameter is created without an SqlType, which is the reason this exception is thrown from DriverBase during the call to Session.List. It appears to only use the constructors with a SqlType on an HQL or unnamed query.

I can't use HQL because of my subclass provides an alternate way to populate lists with complex SQL that uses columns not in the NH class mappings.

I am at my wits end with this one, anyone have any insights?

It appears that when I use the exact same named query but assign a single Int32 value to the named parameter instead of the ICollection list of values, the query works. The Typed Value gets built properly in both, SetXxx functions, but later on a Parameter object must be built with a type for the SetInt32 that is not happenning for the SetParameterList as I explained in previous post.

I would like to get the latest build of the Alpha, but I am having trouble finding it. I only see the 5-28 build.

I may also try and get Nant set up, (another goal with no time for at the moment) and build NH with a possible fix. I am having signature problems when I just build NHibernate.dll (I understand why, just need a quicker way to resolve it).
