Hier Block - Message and Stream Ports - Port of Of Range

I have a hier block with a couple of message i/o and complex stream i/o.
After including the hier block in a top_block and running, it threw out
an
error about input ports being out of range. It turned out that it had
assigned a port index to a message input, so the stream input had been
displaced to higher indices that didn’t actually exist in the io_sig.

As a work around - I deleted all of the pad sinks/source in the GRC
file,
added the stream sinks/sources, and then messages, to assure that the
hier
block generator assigned stream ports to the lower indices. [ I was a
little surprised this worked actually].

I can try to track down the cause, but I thought I’d mention it here if
someone knew exactly where to look.

Or maybe I’m just doing something silly?

I can actually see this being an issue. There is some ambiguity about
port
ordering between the message and data ports. We’ve looked at them a bit
in
the past for similar bugs, but I can see a problem with hier_blocks,
particularly when built in GRC.

Your workaround also doesn’t surprise me :slight_smile:
