Re: Struts2 iterator tag
Hi Laurie, thank you for help!
you are right that's what I want: to push back the updated fields into the
list.
And then I want access the updated fields in the update action class .
I think maybe there is somesthing wrong in my tag syntax? I found out that I
must use "{}" instead of "[]" which is only for maps, but it also doesn't
work.
I try this example but it doesn't work:
http://www.vitarara.org/cms/struts_2_cookbook/updating_a_list_of_domain_entities
Is there any other example anywhere, which I've not found?
I'm really desperate! What I want is not unusual, I've thought.
This must work til tomorrow (for my company) :-((
Thank you very much for helping!

Re: Struts2 iterator tag
...thank you for the answer!
But I've read, if I want to change the complete list with the submit
action. I must use the list index.
If I make a submit in each row I can use "destination" syntax.
Isn't it right?

Struts2 iterator tag
Hello,
I'm struts(2) newbie and I need some help for the iterator tag.
How can I access to an updated list in the action class?
My JSP looks like:
-
Action class:
public class DescriptionTestAction extends ActionSupport {
private List descList;
public DescriptionTestAction () {
}
public void setDescList(List descList) {
this.descList = descList;
}
public List getDescList () {
return this.descList;
}
--
The descList is a spring Bean and everything works well except the update
process.
If I make an update for the destination field e.g. and then submit this form
the descList contains the old values! I've tried everything and spend lot
of time for searching for a solution, please help!
Thank you in advance!
