so if i got you right, there is no way to handle form processing in a called
block, because all information of the request is lost?

That would be a real show-stopper.

Url Parameters (the ?var=xx stuff) is not a big problem, since it could be
set e.g. to the requested page name and so the URI can be put to the called
block. I have that working here.

But this way cannot be used for POST variable. Its hard to believe that this
is impossible with current code.
