Don't render the scene twice.

[chirag04]

from my conversation with @brentvatne on slack. I will try to post repro code soon. Keeping this as a placeholder here on github so that it's not lost in the slack conversations.

Any luck reproducing this?

[chirag04]

ok. I think I can reproduce this in my app now. I will post an isolated case in some time.

I think it happens when you dismiss a modal. (remove navigator)

[chirag04]

damn. After debugging, it turns out to be createFocusableComponent which re-renders the scene when it gets focus after a pop.

seems like by default all scene are focus aware and re-renders when they gain focus.

@skevy any way to avoid this?

[brentvatne]

re-ping @skevy, as I know you're looking into ex-nav stuff atm

[mnichols]

the rerendering on pop just bit me too FYI. The renderLeft component of my route.navigationBar config gets rerendered and not unmounted as I'd expect

Same here, doing a console.log(route) or console.log(props) in renderLeft will print twice
