Nothing wrong with that (in the validate() method, for example), given that you're ultimately going to need to convert to an integer to use in your model tier. From a performance perspective, you might consider keeping the converted value and making it available (to your Action) under a different property name in order to avoid doing the conversion again. > (Have been meaning to check out the java.text.NumberFormat stuff but always > had more interes... uh... important things to do first and havent had time > yet...) But necessary if you want to allow your user to stick commas and decimal points (or the reverse for countries that do it backwards :-) in a Locale-sensitive manner.
