Have you done any performance testing on this? I would have question
about invoking OGNL for each binding.
Performance optimization is left as an exercise for the reader :)
It's definitely more expensive than a straight binding, no doubt. We
do the same caching for class KVC as for instance KVC, so that is
actually not so bad, but the ognl dynamic dispatch is sort of a black
box. I know they have done a lot of performance work on OGNL, though I
haven't explicitly benched this feature (note that we only make OGNL
bindings out of helper function bindings, not every binding). That
said, RoR may not be the fastest thing around, but it's pretty high in
developer productivity -- most apps aren't the music store :)
We have to find a happy medium, the Association factories are quite
efficient and the overhead is very minimal but there is a bit more
code to write, although we could probably template a lot of it.
Agreed.
As for the comments in bindings I agree. I have not had time to look
into it, would you like to?
Yeah sure.
