That's ok. But now I have a problem that at the time an error
occurrs the page is partially rendered already. Is there
an easy way to force a reload of the page which is able to render
to changed state (show:)??
If there is no easy way would it be possible to generate a
continuation url and redirect to it? If yes I would be very if
you could point to some example. I saw that I can register a Block
as a continuation but this will also operate on the component at
the moment the error occurrs (the continuation is created), right?
