Taavi K=C3=B5osaar commented on NH-933:
----------------------------------

Furthermore i seem to get an exception "Cannot use collections with InExpre=
ssion"), when trying to give an array of items into the Expression.In().

Looking at the code, i see this:


if (criteriaQuery.GetTypeUsingProjection(criteria, this._propertyName).IsCo=
llectionType)
{
  throw new QueryException("Cannot use collections with InExpression");
}

The method seem to allow the collection type, but at the same it throws exc=
eption when you try to send in an collection (array).

Id say this is more serious bug.
