Matthijs Wensveen commented on WICKET-12:
-----------------------------------------
Nobody is saying that this should be done without javascript, just without Ajax!
When a page is shown that has a modal window that needs to be open without some
user action that provides an AjaxRequestTarget, this is very hard to do. A
workaround would be to use AjaxSelfUpdatingTimerBehavior and use that target to
open the window, but this is slightly ugly.
Unfortunately ModalWindow.getWindowOpenJavaScript is private, otherwise a
subclass could use that to output to the response (onLoad or onDomReady or
something).

> Reporter: J.W. Janssen
> Assignee: Johan Compagner
>
> Wicket 1.2.2 included a new Modal Window component. However, this component
> can only be used with a valid AjaxRequestTarget. It would be useful if Modal
> Windows could be opened programmatically at any time without an
> AjaxRequestTarget.
