I don't know about that, but you can find out if you make a component
that implements two interfaces and commands that manipulate the same
variable (initially set to 0). For example have one command set the
variable to 2 and have the other command divide the variable by 2, and
on both commands set that value to the leds. You'll know which command
was called first according to the value set in the leds.

Hugo
