Composite id's on columns with null value doesn't work anymore

Description

In version 2.1 a mapping like this worked perfectly even with null values in the key columns:

With the new 3.2 it doesn't work anymore. If one of the key columns contains null values Nhibernate will return a list with the correct number of items but with every item null.

Is this by design?

Just spent 2 hours on 2 person to realize that there is actually known bug. Very unexpected behavior and there are no exceptions thrown about this...
our version 3.3.3 sp1

Funny issue when deleting collection elements where I suspect that the parent is using a composite key: http://stackoverflow.com/questions/19612354/nhibernate-delete-sql-null-check-issue
