[Rock-dev] tools/syskit/lib/syskit/network_generation/dataflow_dynamics.rb:118:in `+': nil can't be coerced into Fixnum (TypeError)

[Matthias Goldhoorn]

I got the folloing error during the start of some components.

I debuggt this and in
syskit/network_generation/dataflow_dynamics.rb

in the sample_count function the triggers map is empty.
i workdaroung it by adding this in the function:

105                 if triggers.to_a.empty?
106                     return 1
107                 end


Not sure where this error cames from. I think it's related that i use 
slave-activities that might be unknown until now to roby?

Hints?.
Matthias
