close all child browser windows when parent closes

[Raymond <pp...@hotmail.com>]

Hi people,

I need to do this in my application: close all child browser windows 
automatically when the parent window closes or timeouts or the user logs 
out.

I find it difficult or impossible to do with Tapestry because of the usage 
of PopupLinkRender.

With ordinary web programming I could do it by some Javascript like this:
<script language="JavaScript"><!--
openWins = new Array();
curWin = 0;

function openWin(page) { openWins[curWin++] = window.open(page,'_blank'); }

function closeAll() {
    for(i=0; i<openWins.length; i++) if (openWins[i] && !openWins[i].closed) 
openWins[i].close();
}
//--></script>

But with the Tapestry framework it becomes quite complicated.

Any solution? Thanks.
Raymond

Encapsulate the above logic into a component such as ChildWindowsTracker.
Then create a subclass of PopupLinkRenderer and override the constructURL()
method to generate Javascript to register the new window with the script
generated by ChildWindowsTracker.
