-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Achilleas,
you're right, grc omits one of the pad sinks; that is kind of a bug, but I don't know if the terminology really fits; as it seems, gnuradio does not like you to have input and output pads directly connected. I don't know if this is only a precaution to avoid loops, or if there are actual reasons you can't have this in a hier block. However, can you make the error go away by inserting copy blocks where you directly pass through?
