Thought I'd throw this out in the middle of the week again...
Kind of a conceptual question: how do you format Dates, Numbers,
Currencies, etc. for *form fields* inside the JSP?
I know I could do in in the ActionForm getters, but:
1. I don't know the locate of the user at that point
2. I'd have to recompile the ActionForm every time I want to make a
change to the *view* - seems like a bad practice.
What I'm looking to achieve is something similar to <fmt:format> JSTL tag,
where you can specify a format mask, or even a format "style" defined
elsewhere.
Thanks,
