Re: Forms and Listview questions..?
Hmm yeah, but I might have to give it a second glance. Still I feel it's
kind of odd that the listItem gets the pageModel and not its own model
as model when using it as compoundmodel.

Well, off-hand, I'd expect that the easiest way would be to do it
using markup inheritance -
http://wicket.apache.org/examplemarkupinheritance.html.
Hm the link you gave talks about inheritance for a page. However this
would mean that I had to put the into the form in order
to add stuff to the form right? What about inheritance for a panel, that
way I could use it as a form. However I got some strange errors when
trying todo this. Heres some pseduo
panel.html
panel.java
private final Form form
panel(String id)
{
super(id);
form=new Form("form");
add(form);
form.add(new textfield..)
add(new captcha...);
}
public addToForm(Component child){
form.add(child);
}
Then the extending panels can add more stuff to the form.. Is this
supposed to work?
If I understand it correctly, I'd have thought so, yes, although if
just getting started, I'd be tempted to get things going on a basic
page, then start refactoring.
Ok, i'll try to redo the panel, and if I run into troubles i'll provide
a quickstart...
I then tried doing it with a panel but also ran into
sometroubles.
Also I've been noticing that if you use a compound model with a
listview forexample my page has a compound model called article I add
the listview new listview("comments"). I would expect my item in the
populate implementation to get fed a comment compoundmodel, but it
does only get the compound model for the page, I then have to call
item.getModelObject and set the compundmodel manually. Is this
something that has been overseen, or am I missing the bigger picture?
I think so... Compare this...
HTML:
Dummy comment
Java: (compressed for vertical size!)
class Article {
private List comments = Arrays.asList(new String[]{"Comment One",
"Comment Two", "Comment Three"});
public List getComments() { return comments; }

This is what I meant extending your example a but, it feels odd to make
an extra compoundpropertymodel:
class Article {
private List comments=new arraylist...
public List getComments() { return comments; }
}
class Comment{
private String text...
private String author
trival getters and setters...
}
public MyPage(final PageParameters parameters) {
setModel(new CompoundPropertyModel(new Article()));
ListView listView = new ListView("comments") {

setModel(new *CompundPropertyModel*(item.getModelObject()
))
item.add(new Label("comment"));
item.add(new Label("author"));
}
};
}
add(listView);
I see. You can do it like that, but personally, for just a cople of
labels I'd just implement populateItem() as follows:
Sure, this was meant to be a simple example.. If you add some complexity
to it it's much simpler to use the compound propertymodel, and theres
not need for all that code calling all the different acessors since this
is what a compoundmodel does.. Im not sure if something else can be
gained if you make it detachable?
