Thank you very much for explanation. But I asked about other.

I have gate on first list. One input connected to bus via wire with
netlabel. This net (with netlabel) is going out bus on other side of schematic and
connected to port. Port has same name with netlabel. On second list
this port connected with resistor.

When I start ERC (Sheet Symbol/Port Connnection option)
it gives me error marker on gate's input
(Unconnected, Floating and etc.)

When I delete bus and connect input to port directly there aren't any
errors and warnings.

Conclusion: Protel doesn't understand connection by netlabels on same
list when I use Sheet Symbol/Port Connnection option.

Is it true? Or I have made mistake somewhere?
