When I was using it (I abandoned it for various reasons), I set "preserveSort" to false. I'm embarassed to admit it, but I can't remember which problem that solved. However, I can say that I concluded that when you see the word "preserve" in a tomahawk component, it means "don't preserve it: replace it with something you don't want". This was particularly true of "preserveDataModel", which I see you've set to false (as I did after trying to figure out why my table model was reduced to just the displayed rows).
