I'm using GnuRadio 3.6.5.1 and I wanted to create a block similar to stream-to-streams for messages. In the XML I used a variable and nports so I could specify the number of ports in the flowgraph. However, I've found that this does not work. Whenever I change the variable value to something greater than 1, the variable ID turns red and the number of ports displayed does not change. Simply changing the port type to something other than "message" works correctly. Does anyone have an idea how to fix this?
