I'm still a bit confused by this. When I use a standard
ActionForm I don't have to do anything special with my ArrayList
in the ActionForm. A page that uses this ArrayList works fine.
However as soon as I try to use this ArrayList as property in a
DynaActionForm I run into problems trying to submit a jsp page
that was populated with the ArrayList info (the display works
fine, it's just upon submission).

What if the information in an ArrayList of beans that you want in a
DynaActionForm is to first be populated by some database info.
Do you need to first initialize it like a above to a bunch of
nulls? If so what if the list size fluctuates (hence use of
ArrayList) how do you know how many to initialize the ArrayList
with?
Thanks for any more thoughts.
