Bidir pins together ?

Hi, I'm currently trying to connect two bidir pins together in a schematic with quartus (as you can see on the picture) but, i don't why, i get this error : BIDIR pin "xxx" feeds BIDIR pin "yyy"...

you can't do that. without control logic, should a pin be input or output ?? in which directions should the sinal flow be from left to right or vice versa ?

you need to control that with an output enable
