Ah yes, stacking and nesting - looks good.
Some time back the Wicket dev (Igor or Sven?) who created the
ModalDialog chatted to me about him planning to create ModalDialog - it
sounded like a great idea. I am the developer of Wicketstuff ModalX
library that aims to make the creation of Modal dialogs (using
ModalWindow) in Wicket as easy and generic as it was in 90s era
windowing desktop frameworks like Swing (Java), MFC and OWL (C++).
It looks like ModalDialog is a major improvement on ModalWindow.
One of the things ModalX did was to achieve a completely generic
approach (at the markup and Java levels) whereby any modal could be
opened from any component on any page without needing to add specific
markup to any page or panel markup.
It did this with via an implementation of the ModalX ModalMgr which has
an allocatedModalWindow and releaseModalWindow. An app's common base
class Page would implement ModalMgr and establish a list (e.g. 5) of
form objects wrapping ModalContentWindow objects used as placeholders
for the generic modals - then any code, anywhere could pop up whatever
dialog it wanted without that specific page or panel needing to have
it's markup specifically changed to hold that dialog.
I guess ModalX's ModalMgr's allocated list of ModalContentWindowS is
closest to the ModalDialog example's 'stacked' mode.
The ModalX ModalContentPanel extended Panel and had all the "smarts" to
operate as a Modal panel within the context of a ModalMgr - e.g.
automatically calling releaseModalWindow to effectively return the
ModalContentWindow to the 'pool' when it was closed.
From what I can tell the aims of ModalX can now easily be achieved
using the new ModalDialog class and either:
- ModalX is no longer needed for Wicket >= 9 (except for apps continuing
to use ModalX via current ModalWindow implementation)
or
- ModalX could be reimplemented using ModalDialog so that existing
projects using it can continue working without any code changes but
using ModalDialog under the hood instead of ModalWindow.
I guess in the short term at least, as ModalWindow is deprecated and not
removed, existing ModalX code will continue to work fine in Wicket 9.

It is possible to stack ModalDialogS like we could stack ModalWindowS?
e.g. In a page a user opens a parent modal that has a "Details" button,
which, when clicked, pops up another ModalDialog over the parent
ModalDialog
The new example in Wicket-Examples module shows this.
