I think I know the problem. If you are calling this method as a value expression during the render phase of the JSF lifecycle, its not going to work. What you need to do is understand the JSF and servlet specs: There is no way I can send a redirect after I have already started to render the response. So Seam doesn't try to do that. So, if you need to do this kind of thing, you need to do it in a page action or something, not while evaluating a value expression. This is described in the documentation, of course.
