Unfortunately, we can't do anything like that on default UIData
implementation
(it could breaks backwards behavior). I think we could include a property
on tomahawk t:dataTable called "readOnly", that just skip all that code
related to save/restore for rows. That could be better, and it has sense to
put in tomahawk, because after all that is the right location for extend
default jsf components.
Anyway, I think it is possible to do some work on UIData to make it perform
faster and better.

I don't think in this case it applies, but any configuration param for a
view
should be on a tag like f:view or something similar.
