Yeah, it looks like it goes all the way through the Ognl stack and out 
to the ObjectFactory. Not sure why this is happening since supposedly it 
should handle arrays, collections, Maps, etc. I'm gonna grab the Ognl 
code and see if I can track this puppy down. If anyone has info, please 
send it my way.
