Maybe there could be some APIs added for setting the scoping of caching of resolution of expressions? I can think of some cases where #{bean.dataModel} should be evaluated once per render, or where it should be evaluated over and over. So why not have some hint? With Facelets there's the c:set tag, which does not cache the evaluation. Maybe one could be added that will. And then, for dataTables, and other UISeries, there could be some means of them setting a hint on their row var, so that that part of the expression is only evaluated once, while in the context of each individual row.
