I think we need a RedirectToExternalException extends
AbortRestartResponseException that sets the RedirectRequestTarget to
an external page. Isn't too hard to implement I suppose...
public class RedirectToExternalException extends
AbstractRestartResponseException
{
private static final long serialVersionUID = 1L;
public RedirectToExternalException(String url)
{
RequestCycle rc = RequestCycle.get();
if (rc == null)
{
throw new IllegalStateException(
"This exception can only be thrown from
within request processing cycle");
}
else
{
Response r = rc.getResponse();
if (!(r instanceof WebResponse))
{
throw new IllegalStateException(
"This exception can only be
thrown when wicket is processing an
http request");
}
// abort any further response processing
rc.setRequestTarget(new RedirectRequestTarget(url));
}
}
}
