Hi All,
I have a lot of work with ModalWindows in my project and want to use objects
which created on the base page and are changed in the modal windows.
I found that ModalWindow was changed in wicket 1.5 and want to ask about
solution.
Please see short example:
// Base Page
public class MyPage extends WebPage
{
public MyPage()
{
final ModalWindow window = new ModalWindow("window");
add(new AjaxLink<Void>("link")
{
@Override
public void onClick(AjaxRequestTarget target)
{
final CustomObject object = new CustomObject();
window.setPageCreator(new ModalWindow.PageCreator()
{
@Override
public Page createPage()
{
return new MyModalWindow(object, window);
}
});
window.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback()
{
@Override
public void onClose(AjaxRequestTarget target)
{
if (object.isValue())
{
// This code is never executed {1} in wicket 1.5. But it
worked in wicket 1.4
}
}
});
}
});
}
}
// Modal Window
public class MyModalWindow extends WebPage
{
public MyModalWindow(final CustomObject object, final ModalWindow window)
{
add(new AjaxLink<Void>("link")
{
@Override
public void onClick(AjaxRequestTarget target)
{
object.setValue(true);
window.close(target);
}
});
}
}
As I understand - the reason of this behavior is serialization of pages.
I also know one solution - use PageReference(same with example here -
http://www.wicket-library.com/wicket-examples/ajax/modal-window?0).
But I want to ask - is there another solution? Use PageReference is not so
flexible.
For example I have a lot of modal windows which are opened from the panel.
In this case I have to search my panel on the page. Moreover I can use one
panel from different pages.
Other problem - I don't want to use global variables on the Base Page - I
want(ant in several cases I should) use local variables.
Can anyone give advice - how to simplify usage of modal windows in such
cases?
