Well, I'm providing as attachment my CompositeActor code (which doesn't work properly) along with the model that should use it.
Ideally the output should be:
"
Hello muhannad
Hello ali
no input
"

but what I get is:
"
Hello muhannad
Hello ali
Hello nothing
"

any help please?

Thanks!

Best regards,

Muhannad
