Hi Toni
there are several different approaches. The one I use has an Edit action and a
Save action. The Edit action fetches the dropdown list and puts it in the
request and results in the form jsp.
The form submits to Save and if validation fails, the Input result is
resultType=chain and
Well, for the retrieval I use stateless session bean injected to the action
with Spring, like this (simplified):
public User getUser() { return user; }
public String edit() {
user=dao.get(id);
return SUCCESS;
}
So it's nothing special.
The session approach of course isn't ideal, but more a
I think so - the chain is just a forward inside the same request so you
shouldn't lose the field errors. But I'm just setting up a new website now with
this approach, so actually I'm as inexperienced as you are - my previous Struts2
project had a different approach entirely.
You second
Thanks for the answer! Does the resultType=chain approach preserve the
fieldErrors and the values the user has already typed into the form? Also,
how do you prevent the edit action from retrieving the entity from the
database in the case the validation fails?
I also thought about putting the
Hello,
What is generally regarded as the best practise for populating a select
element in a form from database so that it works regardless of the action
and the result from which the form is displayed?
I've tried this:
action configuration:
action name=edit method=edit class=admin.Users
Yes, I get the picture. If you haven't already, download the source bundle and
look at the examples.
Actually I don't think I understood one thing you said. You're using an action
taglib in the JSP, which invokes the list retrieval. Surely that's not affected
by validation failure? I was
Yes it shouldn't be affected, but there seems to be a bug that affects this
behaviour, see WW-2599.

Did you see this:

I stumbled across it on the wiki. Do you exclude the appropriate 'read' method
on your validation interceptor config? You don't want struts to think that
validation
Toni,
Isn't your bug a duplicate of
