Add a "bool is_child" parameter?

[merkulova, 2015/03/04 19:06:49]

what for? do you think it will become useful?

Also it looks like then we can use the observer instead
PropagateChildStatusToUser. But there might be
issues with ctors of User class and CAService class synchronization then.

Yes, I'd expect so - if you're interested in changes to the child state, then
you probably want to know the new state. And it just seems weird to tell the
observer "hey, this changed", but not tell them what it changed *to*.
It would be great if we could get rid of PropagateChildStatusToUser! But I'd
leave that for another CL.

Done.
