Hi,
thank you Marcus for your fast answer. Well, the problem is that nobody
ecept scheduler knows when the flowgraph has finished, so I don't know who
should sent that message to the block. This is however not of crucial
importance for me. Namely I wanted to test some of my custom blocks, and
test flowgraph necever reached completion, but as soon as message accepting
dummy block was out everything was fine.
Best,
Nemanja
