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!
