hello,
is the following true?
1) if I do a logic:iterate over a Collection when viewing the items in the
Collection, I can use e.g. a HashSet
2) if I do a logic:iterate over a Collection and I want to be able to also
update the items, I need to use an indexable Collection, e.g. an ArrayList.
HashSet won't do.
Using an indexed collection will certainly make life easier, as Struts
can then update the collection 'in place'. If you use a set, you'll have
to reconstitute the entire set from the request parameters. Whether you
*can* use a set depends on exactly how you're using it.
