[Seaside] WATask and browser re-direct

[squeakman]

Greetings,

I have the following in a WATask:

MyWATask>>go
    self call: RedirectThing new.
    self halt.

The component RedirectThing does a browser redirect with code like this:

RedirectThing>>updateRoot: anHtmlRoot

    anHtmlRoot meta redirectAfter: 2 to: self redirectUrl

I do get to the redirected page but control never gets transferred back 
to the "self halt" in MyWATask>>go.

Is there some way to call #answer: from RedirectThing so that control 
goes back to MyWATask>>go and still getting the redirect to work?

Thanks,
Frank
