So the new Habanero version (2.3.2) is out, and one of the new features is an improvement in loading collections in the form of an IN operator (and its negative, not in).  This works similarly to how it's used in SQL - in fact it gets translated into a SQL in clause if your Habanero app is running against a database.  Here's an example of using it in loading a set of Person objects:

BusinessObjectCollection persons = Broker.GetBusinessObjectCollection( "Surname in ('Wiles', 'Powell', 'Naidu')"); It's a really intuitive syntax because of its close relation to SQL's in statement.  Also available is the 'not in' operator which does exactly what it says - searches for items not in the given list.

If you want to load using the more type-safe Criteria objects, or you are using code to build up your criteria clause, you can do it like this:

object[] values = new object[] {"Wiles", "Powell",...
