I didn't think it would cause a problem. I'll look
over it again. If a field is of type int, you don't
need to validate to see if it is an int. Also if you
have a field defined as an int, then you don't know if
someone entered something bad because you will always
get the default value of the field. So on the
ActionForm level it is good to preserve the user's
input so if it fails validation you can return the
value the user entered so it can be corrected. So an
ActionForm normally uses Strings except for
checkboxes, radio buttons, and select boxes where you
know the user can't enter anything bad. Then you can
have a bean with all the correct types (int, Date,
etc.), and convert the ActionForm's values to the
other bean. There are a couple of transformation
packages posted to help with doing this type of
conversion between objects. Here is the link.
