Ok I got the composite-elements to work within an id bag and let me say they are awesome. So fast to load and they still work similar to entity objects. Excellent. The only problem I'm having is the Primary keys are not being set in my java object. All the other fields are set no problem. And I have played with it to the best of my ability. Middlegen will not generate the java object for the Projectcompound class listed below, so I had to write it by hand. Perhaps I wrote it incorrectly. The mapping works extremely well and everything else is fine, I just can't get the pk so it's difficult to update the object. Is this by design? Am I doing something lame? Thanks.
