[T5.4] cannot redirect on session timeout

[Geoff Callender]

The technique I use in T5.3 isn't working in T5.4 (alpha-23 with jquery).
Has anyone else got it to work?

Server-side, I'm returning JSON response containing
<code>redirectURL</code>...

OutputStream os = response.getOutputStream("application/json;charset=UTF-8"
);

os.write(("{\"redirectURL\":\"" + requestedPageLink.toAbsoluteURI() + "\"}"
).getBytes());

os.close();

…and client-side, the response is being handled in pageinit.js method
handlePartialPageRenderResponse.

        responseJSON = response.json || {};
        partial = responseJSON._tapestry;
        delete responseJSON._tapestry;
        if (partial != null ? partial.redirectURL : void 0) {
          window.location.href = partial.redirectURL;
          return;
        }

In debug I see that <code>response.json</code> holds redirectURL. That's
good. But <code>partial</code> is undefined so the redirect doesn't occur.

Is this a bug or have I missed something?

Cheers,

Geoff
