"transmit_pma0" must be connected to an output pin

Hello all.

I'm try to use alt_gx in Arria-2. I'm make a megafunction with ALGGX (protocol - basic and subprotocol none). I'm connect tx_dataout pins to top_level design. Set io to 1.5v PCML. Grag and drop my tx_dataout to pins from GXB_TX8p (and n) to GXB_TX11p (and n). But when I build projects quartus say "Error: Output port dataout of the GXB transmitter channel PMA atom "transmit_pma0" must be connected to an output pin". But I'm sure that I connect this pins to GXB TX pins in same bank.
