Yes. Hibernate 3.2 provides support for a feature that's been missing for the 
past year & a half that relates to outer joins on optional parameters. To date, 
we've had to drop to SQL queries to support this, but HBN 3.2 removes this 
limitation and provides full support from the Criteria & HQL query objects.

Personally, I'm not yet the expert in this area - my colleague is. So, that 
said, I may have slightly misstated the issue. I apologize in advance!

For jBPM, we'll need this capability to support our retrieve tasks use case, 
which will support filters / sorts above and beyond what jBPM provides 
out-of-the-box.
