Ok, except remember this is in a ListView so for each ListItem that I
set the callback for, the single instance of the modal window is being
updated to the latest callback. So when it fires, it will operate on
the last item in the list.
ie with your method
- create a modal window for the entire list (thats what I need)
- iterate over 5 items
- setup a callback for each item to update the text bits I need
-setup an AjaxLink for each item to open the window
- in onClick for this link, set the content for the window
- ModalWindow takes over and does some processing
- ModalWindow closes, callback updates a label.
Having one MW and one callback per list is working, I set the models
for the things that need to be updated and actually refresh them to
pickup the changes if it was successful, all in one go.
WDYT?
cheers

So you setup a callback when you set the content on the

could work nicely as well.
Yes:
modalWindow.setTitle(xx);
modalWindow.setContent(yy);
final AjaxButton ajaxButton = this;
modalWindow.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback() {
public void onClose(AjaxRequestTarget target) {
// Do your magic here
...
target.addComponent(form);
target
.addComponent(AbstractInnerPanel.getFeedbackPanel(WizardPanel.this));
}
});
modalWindow.show(target);
MarkupUtils.resizeModalWindow(target, 850, 400);
Here's the new structure for your perusal:
Your java was the curious part, but try the example above, position
the close callback together with showing it.

Ok so I was doing that before but had an instance of a
ModalWindow per
ListItem, and the associated callback for each. Because it was all
inside,
it was self contained so I could do all the updating easily. But
this
mean
many MW and callbacks per page.
Sounds wild..
This also means the callback is outside so it doesn't know about
the
object that was clicked. I did this so it reduces the total
number of
objects
on the page.
Why not put the callback inside too.. I do that.

this.
Why don't you already add all the necessary children to the
ajaxRequestTarget here where you have the references?

I've got one Modal/handler per ListView so it needs to know

update it, even if it gets its text from that model yes?
No. You can update multiple components with
ajaxRequestTarget.addChildren or you can differentiate with
component
class if absolutely necessary. Or you can repaint the whole
listView.

Thanks.

It would be better design to make the span update itself
using an
abstract readnly model:
new Label("automatic", new AbstractReadOnlyModel<String>() {
public String getObject() {
return "whatever value you need" +
getSession().getCurrentValueOrState();
}
});.

Yeah that sounds like what I need. I need to update some
text in a
span
thats inside my ListItem once I do some processing.
Thanks,

ListView returns an iterator of ListItems
Each ListItem is a component so you can just do
listItem.get("component_id");
Does this sound like what you were looking for?

Hi all,
I have a ListView and need to be able to get some child
items of
a
particular ListItem, ie some spans, so that I can update
their
Models.
How
can I target some markup elements inside the ListItem
container
(ie
TR
tag)?
Thanks,
Steve
