Problem solved.
I had both <wicket:head> and <head> sections in my html and the
FormModificationDetectorBehavior was being attached twice. This was
causing a "too many recursions" error in the javascript and the code was
dying. Pulling out the <head> tag and placing everything within
<wicket:head> cured it.
It's working again.

The problem appears to be related to the code I used to replace the
old onAttach code. It was:
////////////////////
protected void onAttach() {
super.onAttach();
if (firstTimeThru) {
final WebMarkupContainer c =
this.getBodyContainer().getBodyContainer();
c.add(new SimpleAttributeModifier("onload",
"FORMCONFIRM=true;FORMISDIRTY=false;"));
c.add(new SimpleAttributeModifier("class", "body1"));
c.add(new SimpleAttributeModifier("onbeforeunload",
"return warnOnPageExit('Data has changed. Make sure you press
save "
+ "if you want to keep your changes!');"));
firstTimeThru = false;
}
}
////////////////////
now it is:
////////////////////
public void renderHead(IHeaderResponse arg0) {
if (firstTimeThru) {
arg0.renderOnLoadJavascript("FORMCONFIRM=true;FORMISDIRTY=false;");
arg0.renderCSSReference("body1");
arg0.renderOnEventJavacript("window", "onbeforeunload",
"return warnOnPageExit('Data has changed. Make sure you press
save "
+ "if you want to keep your changes!');");
firstTimeThru = false;
}
}
////////////////////
I'm focusing on tweaking this at the moment. Not sure yet what's
going on.

Not yet. Still trying to figure it out. Just wanted to make sure I
wasn't overlooking something in the manual that works just as as well
or better.

I haven't been able to make this work since my upgrade from 1.2.x
to 1.3.5:
http://javathoughts.capesugarbird.com/2007/11/warning-on-page-exit-for-wicket-12x.html
It was pretty slick. I was able to warn the user that she/he had
changed a field without saving when trying to navigate away. Is
there a
better facility in 1.3.x that I can use for the same purpose?
