Hier blocks with message output pads

GNU Radio
1

Hi there,

I am having the following problem:

I create a simple hier block in grc and one of the outputs is
a message. I added an output pad with message port, but I see two
issues:

  1. the colour of the pad connection is not exactly the same as the
    message
    connection (maybe this implies something…)

When I compile the block, the python code does not have any
signature that refers to the message output.

Am i doing something obviously wrong?

Thanks
Achilleas

Like the color difference between “Message Queue” and “Async Message”
ports (see Help–>Types)?

When I compile the block, the python code does not have any
signature that refers to the message output.

Can you provide an example (your files, a screen-shot, a generic
example,…)?

Sebastian,

it turns out that the colour mismatch was not the issue here (your
pointed
questions
made me realize that).

There must be a problem with hier blocks with 4 or more ports (one of
which
is an async message)!!!

I attach here a trivial example.

I will also repost this question under a separate title on the mailing
list…
