Hi Juju,

I think I read at some point in the official document that you can't set state from hook.

However, this is what I'm trying to achieve: in @hook('config-changed'), I will pass in a file path as a config value. Files are part of the charm so they are installed in /var/lib/juju/agents/unit-mycharm/myfiles/ on the unit node. But when @hook('config-changed') is triggered, my code to "open('/path/file')" actually complains "file not found". This makes me wonder that hook is not visible of the charm directory?

So I'm thinking this can be worked around if I set_state("mystate") from hook. But doing so didn't trigger @when("mystate").

What's the right way to do this then?
