I am trying to simulate a system in which I will use "Signal" to communicate between different blocks. The signal will have "attributes" which will carry values associated with that signal. Here is the BDD
Here is the signal tick with TWO attributes insider "Sender" block
Here is the activity diagram that process the tick signal
Now, I get following output which looks strange to me..
So, it seems to me that "tick" signal generated with null values? I have also attached the model. It would be great to know how to solve it. Thanks!
