I think that it's working because of https://github.com/callemall/material-ui/blob/master/src/mixins/style-propable.js#L36 this.context.muiTheme then https://github.com/callemall/material-ui/blob/master/src/utils/styles.js#L28 is probably always false.

I'm fine with it. @shaurya947?

You're right. I'm still not sure how adding contextTypes to <Clock> solved it however.

I'm fine with it too. @oliviertassinari feel free to merge this!

@louy @oliviertassinari I think there's a bug in the prepareStyles method: https://github.com/callemall/material-ui/blame/v0.12.4/src/mixins/style-propable.js#L36

the example from the documentation for <AppBar /> rendering <NavigationClose /> no longer works and triggers an invariance warning: https://github.com/callemall/material-ui/blob/50b4a5b780e3e9dde591fea200226236d62eeb87/docs/src/app/components/raw-code/app-bar-code.txt#L7

I traced it down to the <SvgIcon /> component, which relies on StylePropable.

@jlebensold could you describe a little more as to how you produced the bug? I'll look into it then..

@jeinbensold is it a "you're calling ensureDirection twice" error?
If so, then it's not a bug in the method itself but an incorrect use of it somewhere.
Could you show us an example of that? Docs are working fine for me.
