Re: nested:iterate - set method not called
The setter on a nested property, such as the list properties in my
example, is only there as a convenience. The Struts managing code will
never actually use it. It only worries about the last bean in the nested
property definition. My construtors use it to make the simple example
easier to do.
As for storing a reference to the form bean in all the shild beans...
no. This is probably not model behaviour. I only did it so I could get
my delete buttons working for the banana objects. The setter of the
banana's object knows that the bean is to be deleted as it's been
called. The reference to the parent bean is there so it can call the
parent bean and tell it that it wants to be deleted.
If you don't need this more advanced bean driven functionality, then you
really should avoid it.

Re: nested:iterate - set method not called
Thanks for the reply Arron, ... well appreciated.
but I noticed in your example that the MonkeyBean contains an ArrayList of
monkeys (ArrayList monkeyList) and you have both a setter and a getter
method for it. I was trying to duplicate this on my form bean. My
ArrayList is contained in the FormBean itself. That's why I was expecting
the setter method in the formbean to be called.
Also, is it necessary for the beans contained in my ArrayList to a reference
to the form, much like you have a reference to the BananasIncorporatedBean
from the MonkeyTeamBean.
I apologize if these are simple question, I've struggle with this for 2 days
now and the project deadline is not budging.

Re: nested:iterate - set method not called
The getter will only ever be called, as it's the middle-man.
The system only wants to set the "name" property on the nested bean. It
will call the getter of the "extrainfo" object to get at the nested
bean, and then set its property. Never actually calling the setter of
the parent bean property.

RE: nested:iterate - set method not called
Ahhh, sorry! You are passing in an array of objects. I should read before
replying huh?
Check previous posts for this. I seem to remember something about providing
setItemId methods being used for indexed page elements?

Re: nested:iterate - set method not called
thanks for the reply, Scott
My syntax looks okay on the jsp side and since the getExtrainfo method is
being called it puzzles me that the set method is not being called on
submit.

RE: nested:iterate - set method not called
Could it be that the html field in your jsp is named 'extraInfo' (uppercase
'i'), and the setter is using a lowercase 'i' in the word info?
