Re: Strange bug when querying a circular graph with several joins

What version of c# and nh are you using?

Here's an extension method that I use for these type of of problems

public static ICriteria CriteriaByLongAlias(this ICriteria criteria,
stringfield)
{
 ICriteria byAlias = criteria.GetCriteriaByAlias(criteria.Alias + "_" +
field);
 if(byAlias == null)
   byAlias = criteria.CreateCriteria(field, criteria.Alias + "_" + field);
 return byAlias;
}
Use this as follows:

ICriteria criteria = NHsession.CreateCriteria(typeof(Role));
ICriteria primaryLocationCriteria = criteria.CriteriaByLongAlias(
"PrimaryLocation");
ICriteria addressCriteria = primaryLocationCriteria.CriteriaByLongAlias(
"Address");
addressCriteria.Add(Expression.Like("Postcode", "BS%"));



If you review CriteriaImpl.cs you will note that while CreateAlias returns
the original criteria, CreateCritieria returns the subcriteria. I've found
it best to ignore CreateAlias.
