this is terrible. can someone please help me explain it better?

[sophiebits]

Honestly, this is very confusing so I'd try not documenting it for now. If people ask questions that this will solve then we can try to explain it better then. Until then, I think having it listed here will confuse more people than it'll help.

Excuse my ignorance, but where is componentDidMount used, I only see componentWillReceiveProps and componentDidUpdate in ReactTransitionGroup? Those test cases seem to imply componentWillEnter and componentDidEnter are not called until second render?

[petehunt]

They are not called on the initial render of the transition group, only when they are added to an already mounted transition group

[petehunt]

...which should probably be documented

[chenglou]

@plievone yeah that's right. I think the rationale is that animations are not desired during the first render, as you might want to directly display all the items. This way is more flexible as you can just manually call whatever animation api if you want on mount.

Ok I see -- I just mixed up the lifecycle methods in group vs child when skimming the code. This will be very handy!

[sophiebits]

Maybe:

This is called after the callback function that was passed to componentWillEnter is called.

[sophiebits]

Can you update the transitions example too?

I stole the code change because I wanted to try to get a final build together. I'll let you wrap up docs :)

Ping? I'm going to cut tomorrow at some point and would like to not have to double land docs.
