Hi all,

gschem supports multiple sub schematics in a single symbol, simply by
inserting multiple "source=xxx.sch" attributes.

 From gschem this works fine. Pressing "S" to go into the hierarchy
opens the first sub schematic and navigate with "page up" "page down"
works as expected.

Now I want to connect a net between sub1.sch and sub2.sch and I use
in-1.sym with net=SIG1:1 and on sub2.sch out-1.sym with net=SIG1:1

If I now run gsch2pcb on the master.sch which contains two of the
symbols with each have sub1.sch and sub2.sch in it, it complains about:

error: net name conflict across hierarchy: net name `A2/SIG1' is used by
net `SIG1' on page `A2/' and by net `SIG1' on page `A2/'
error: net name conflict across hierarchy: net name `A1/SIG1' is used by
net `SIG1' on page `A1/' and by net `SIG1' on page `A1/'

What makes me wonder is, that both "pages" have the name only by the
attribute of the "master" symbol but no page related one. So seeing
"A1/" two times instead of "A1/xyz" and "A1/abc" can be the problem, but
how can I achieve setting correct values here?

Thanks
  Klaus
