The relationship between the view (JSP) and the model (Java Beans) are often
not
as simple (unless you are doing some simple apps) as Struts want/need them
to be. Sometimes what the view need to display is based on the information
provided
by the model, but not necessarily exactly like the model, furthur maniplulation
of the
data is often needed. Seems to me there are a lot of real practical problems in
large
apps are not addressed by Struts.
By the way, I am sure some of my problems are caused by a lack of
understanding
of Struts, I only been looking at it for a few hours in the last two days, so I
am sorry
if I missed something in the docs.
Let's take an example, let's say I have a form with 50 fields filled with
text, combo
boxes and what have you html controls up there. Currently I am handling that in
this
fashion: I name the controls smartly for those ones need to be updated, for
example,
fldName, fldAddress, etc, by the time of the update, I simply loop through all
controls
with fld prefix, and update a xml tree based on the values.
So what's so good about this approach? well, I never have to make any changes
to
my underlying objects like those formobjects struts are so fond of. I can add any
fields
on the form as I wish, and my xml tree would grow accordingly. I perseve my state
in the xml tree.
Maybe Struts addresses this problem in a different way?
