Re: [Discuss-gnuradio] Help needed with message ports

[Michael Dickens]

A quick followup on progress on this query:

The issue is in lib/flowgraph.cc, where message connection edges are not being 
used when counting connections (just stream connection edges). So, the 
flattened flowgraph shows 1 connection (the stream one going out), but no 
connection is found (because the message one isn't being counted). I believe 
that this issue would also happen with a non-hier2_block, but I'm not sure.

Now that I understand the basic issue, the big question is how to fix it. I'll 
keep prodding & once I get my mind around it & get a patch, I'll issue a PR & 
tag you on it, Volker, for testing. Cheers! - MLD
