It doesn't seem to work correctly when I click an

that looks like the normal WebObjects session timeout page with
a bit of javascript tacked on the end; in fact, if I peek at
redirect.contentString(), I get
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<title>Missing Session Error</title>
...
</html>
document.location.href='/cgi-bin/WebObjects/WOPrefixReg.woa/wo/

Any idea why the <script> etc. is left off in the tab case?
That is not the question. The question is why that HTML is in
there. It looks like it is getting generated _before_
AjaxUtils.redirectTo(errorPage) is getting called. Is there
anything going on before this in your exception handling method?
Here's my code:
public WOResponse errorPageWith(WOContext aContext, String title,
String message) {
if(aContext.hasSession()) {
aContext.session().terminate();
}
And there is your problem! ERXRedirect is returning a re-direct to
a component action URL which needs this session. Move this code to
ErrorPage in appendToResponse and set the session timeout to a
second or two instead of calling terminate() directly.
Thanks, but... what if this is all because of a session timeout in
the first place? Even if I remove the the session().terminate()
entirely, this still happens.
Now that is an interesting question. You would either have to
redirect to a direct action that returns your error page, or create a
new session to use in this redirecting code.
Hmmm, that is a bit of a mess.

ErrorPage errorPage = pageWithName(ErrorPage.class,aContext);
errorPage.title = title;
errorPage.message = message;
if (AjaxUtils.isAjaxRequest(aContext.request())) {
// Create redirect to return to break out of Ajax
AjaxUtils.redirectTo(errorPage);
WOResponse redirect = errorPage.context().response();
// Generate the error page so that it gets into the page
cache, don't do this earlier!
errorPage.generateResponse();
NSLog.out.appendln(redirect.contentString());
return redirect;
}
return errorPage.generateResponse();
}
@Override
public WOResponse
handleSessionRestorationErrorInContext(WOContext context) {
super.handleSessionRestorationErrorInContext(context);
return errorPageWith(context,"Session Closed", "Your session
has been closed or timed out due to inactivity.");
}
