Thanks, we'll take a look at it. There were some recent changes in that area.

Hi All,
I decided to give 3.10.9.0-rc1 a try today and noticed that message domain signals are shown as red broken connections when reloading the .grc file (e.g. when saving the file, opening a saved file, or when reloading blocks). Is anyone else experiencing this issue?
I've attached a dummy flow graph (and a screenshot) to illustrate the issue. I also reverted back to 3.10.8.0 and the flow graph (and other more complex flow graphs) work as expected
The error message generated for each virtual sink/source is: No connection known between domains "stream" and "message".
It seems to pertain to the "validate" function [1] in "Connection.py" checking the types of the connections, but I'm not very familiar with the inner workings of GNU Radio and wasn't able to track down where/how those types are set for the virtual sink/source blocks.
Thanks!
Jason
