We're use i18n. In addition to the business processes of the actions, we were doing a lot of single message injection, using EL, which required parsing and evaluation of the expression and retrieval from the map. Sure, a cursory assessment says bijection itself is not a problem, but when you have 25-30 value-binding methods called and 5-10 possible validation error messages bijected from your resource bundle, you take a vastly different approach to your implementation.
