Re: Editing a collection
I'm going through something similar right now. Looking at the docs: http://tapestry.apache.org/tapestry5/tapestry-core/component-parameters.html#orgapachetapestrycorelibcomponentstextfield it seems that your: value=user.loginUser determines the field that gets updated when the form is submitted. So as you've got 6x fields that point to the same field in your form, that's what gets updated (take a peek at 'user' to confirm this). I think you need to override the 'value' setting to point to your different objects.
Re: Editing a collection
You mean that using value=user.loginUser tapestry alway update the
same thing.
Thus if I change the method
User {
void setLoginUser(String loginUser){
this.loginUser = loginUser;
System.out.println(loginUser);
}
It should at least output the value I input in my textField ...
And that's right, it actually what's going on the input are correctly
output
But When I outout the user itself in the page
public void setUser(User user) {
this.user = user;
System.out.println(user);
}
the old value is kept
actually setUser is call before setLoginUser ...
Ok thanks I've to work on that.

If you want, I built a ListEditor to handle this kind of things. It's
part of my project, http://interldap.org
What you may looking for is here :
http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/trunk/src/main/java/org/interldap/wui/t5lib/components/ListEditor.java?view=markuprev=672
And here there is an example of use case (it really lacks a lot of doc) :
http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/trunk/src/main/resources/org/interldap/wui/t5lib/components/eschema/EditAttribute.tml?view=markuprev=568
That build a list of input fields, with a [delete] button next to them,
and [add new value] button at the end of the list.
Each button emits an events so that enclosing component can add or
delete matching value from list.
When you click on a button, updated values are set in the list at the
right place.
It may be use to construct simpler list editor.
Hope it may help !

Re: Editing a collection
Hi François
Thanks a lot, but actually my goal was more on understanding the loop
inside the form and how the model is updated in such situation.
I keep your link though, I'll have a look on it.
Michael.

Editing a collection
Hi,
I make some nice night experience about editing a list in a form.
Here is my template
===
t:form
t:loop source=users value=user
t:textfield value=user.loginUser t:validate=required/br/
/t:loop
t:submit /
/t:form
and here is my page
===
public class ListBean {
private ListUser users = new ArrayListUser(0);
private User user;
@PageLoaded
public void initUsers(){
users.add(new User(mic1,pass1));
users.add(new User(mic2,pass2));
users.add(new User(mic3,pass3));
users.add(new User(mic4,pass4));
users.add(new User(mic5,pass5));
users.add(new User(mic6,pass6));
}
public void onValidate(){
System.out.println(users);
}
public ListUser getUsers() {
return users;
}
public void setUsers(ListUser users) {
this.users = users;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
I bump into really strange things ...
1) onValidate is called six time !! Probably as much as users.size() I
guess, is that expected ?
2) Debugging and logging show me that the list of users is never updated
whatever the input in the textfields
Is all that normal or did I miss a key concept
