dynamic form action flow

[Jeff Oberlander <Je...@onename.com>]

Ok, I've wasted an embarrassing amount of time on this and would appreciate
any help.  Its night now and no progress has been made.  This is another
action flow question.  Maybe there is a sample somewhere that does this?  I
apologize that this is long.  

I have an action form that contains an ArrayList of items (lets say phone
numbers). The form allows me to edit existing numbers or add new ones.
When I go to the editPhoneNumbers.jsp page, it displays all of my phone
numbers based on the ArrayList with a button to add another and a button to
save the form. I start with a single phone number - e.g. my home number. If
you hit "add", the form should be re-displayed with 2 phone number fields -
my home one, and a new blank one - both editable.  

This is the action flow I currently have:

editPhoneNumbers.do --> EditPhoneNumberAction.java (input is PhoneNumberForm
- containing an ArrayList of numbers) - this loads my current phone numbers
from the data store into the form.

EditPhoneNumberAction --> editPhoneNumber.jsp - this displays the form.

editPhoneNumber.jsp --> SavePhoneNumberAction.java (action = add | save)

SavePhoneNumberAction.java - if the action is add, I add an empty
PhoneNumber object to the ActionForm ArrayList, then I want to redisplay the
form with the original item, and the blank new one.

SavePhoneNumberAction.java --> editPhoneNumbers.do

Loop is complete.
I thought this would be as simple as adding a new item to the ArrayList in
the form and forwarding on the original form.  It doesn't work.  I keep
getting back (in the display) only my home phone number (the original form
without the new object)  I suspect it is related to this log message:
"Recycling existing ActionForm bean instance of class ".  Another
interesting point is even though I explicitly set the action property of the
form in SavePhoneNumberAction, it always comes into EditPhoneNumberAction as
null.

It may be that this is looking up the original phone number again. 

If so, this is also where the recyling message could be coming into it. 

Do you want to go back through the edit action, or straight to the
display page?
