Rick, what is the real problem here? I ask because what your trying to
do seems reasonable to me and I'd probably do something similar,
although I probably wouldn't use LazyList (I'd probably build the list
manually), but that doesn't really matter. I would *not* use session
for this as I can't think of a single good reason to do so (well, aside
from maing it WORK of course!).
The problem is Frank when you don't use the Session you will get index
out of bounds errors when the form tries to submit since the first thing
done is reset all the form values before BeanUtils tries to populate
them - so that when the form tries to populate the List items you'll get
indexOutOfBounds errors. So for just a one deep List in your ActionForm
it's not too big a of deal since a LazyList will work. (I'm curious how
would you accomplish this WITHOU using a LazyList or using the Session?
- the only other option is in the reset method you make sure you
initialize your list add enough items to your List so that when the form
submits it will cover all your possible values - way annoying since you
need to know the size of the list in the reset method which is a pain -
hence the LazyList is just awesome). I'm running into trying to figure
out the best scenario for populating at least one more level deep. In
other words the source code might look like...
<html type="text" name="foo[3].bar[2].someProperty" value="something"/>
(In my simple case I'm just working with employees[2].phoneNumbers[1] etc)
JSF handles this stuff nicely (although I'm not sure of the mechanics of
how it's accomplished, but it works:).
