aggregate data / dynamic form / DynaForm

[joshua rosenblatt <jr...@hotmail.com>]

I have a DTO that consists of some get/set attributes and then a sorted 
collection of beans each with soem get/set attributes that I want to 
dsiplay.  I need to write these out to a dynamically sized form and let the 
user edit the values before rolling it back up.  There is other data already 
on the page.

I'm already using a DynaActionForm so i would like to stick with that but 
recognize that they dont' work with arrays . . . so i don't see any 
alternative but to switch to a regular action form that would have getter 
setters that take arrays this would transform the beans from a single array 
of objects to a set of arrays of properties and i'd have to create 
transformation logic in the ActionForm.  Is this the only way to go?  Also 
wouldn't there be problems with association?  I would need index 0 of each 
of the arrays to correspond to a row of the form, would that be the case.

Any thoughts on this are really apreciated.

Josh

I find it "good" to have a formBean implement a collction, it makes 
things easier for more complex situations. You can then just do 
bean.next and c:for each and logic iterate work just fine with 
validation, nesting multirow, etc.
