Hi, i want to use a ListView to use the onpopulate method so when the
panel
refresh i can see the new data.But the listView has always one element
and
i
think it was made for lots of elements.
Something is wrong in the way i am thinking.
Any suggestion?

Re: ListView for only one element. Something wrong.
Hi Nicolas,
use more models:
--
class MyPage:
private IModel businessObjects;
private MyPanel myPanel;
myPanel = new MyPanel(businessObjects);
this.add(myPanel);
-
class MyPanel(final IModel businessObjects):
this.add(new SomeComponent(new AbstractReadOnlyModel() {
public Object getObject() {
return businessObjects.getObject().get(0);
}
}));
this.add(new ListView(new AbstractReadOnlyModel() {
public Object getObject() {
return businessObjects.getObject().subList(1,
businessObjects.getObject().size());
}
}) {
...
});

I'm aware that as the panel receives a modelObject and not a model, then
when it's refreshed it will show the previous list. So, I was thinking
about myPanel receiving a PropertyModel(this, businessObjectList), but the
thing is: how can it retrieve the first business object (which needs to be
shown differently) in a "dynamic way" so when the panel is refreshed, it
will take it from the new list (I could use another repeater that will loop
only once, but I was hoping there's a nicer way).
Thanks again,

But the question is: why do you need to refresh your components at all? It
seems you don't use models correctly.
Show us some code.

Re: ListView for only one element. Something wrong.
Hi Nicolas, you can just use a WebMarkupContainer and recreate its children on each request in #onBeforeRender(). But the question is: why do you need to refresh your components at all? It seems you don't use models correctly. Show us some code.
