Did you check the already existing documentation at
http://docs.cor-lab.de//cca-manual/trunk/html/lifecycle.html#lifecycle
However, this and should be extended. Is anything particular missing in this documentation from your point of view?

Thanks!
In State.h I found the following list:
/**
* Possible component states
*/
enum State {
STATE_RESET = 32,
STATE_PAUSE = 31,
STATE_ACQUIRE = 24,
STATE_OFFLLEARN = 23,
STATE_ONLLEARN = 22,
STATE_EXEC = 21,
STATE_LOAD = 12,
STATE_PERSIST = 11,
STATE_OFF = 0
};What is the difference between OFF / PAUSE / RESET ?

This information is indeed missing. Have a look at the rst componentstate definition where there is a bit information on the state semantics: https://code.cor-lab.org/projects/rst/repository/revisions/master/entry/proto/sandbox/rst/cbse/ComponentState.proto
I also just created an overview on the states and their hooks, see attached overview image (a dropped the state transitions for now, as all states can be transitioned to from any other state, which makes the graph quite complex): "on entry" hooks are executed when a state is entered, "on trigger" hooks are executed when a the processing startegy of a component decides to process, and "on exit" hooks are executed when a state is left.
