[RCTConvert] NSString cannot be converted to NSNumber on v0.12.0

[yelled3]

I just upgraded from v0.11.0 to v0.12.0;
After the upgrade I started getting crashes with the following error:

[RCTConvert.m:55] Error setting property 'borderColor' of RCTView with tag #1838: 
JSON value '#dddddd' of type NSString cannot be converted to NSNumber

@ide @brentvatne /cc

UPDATE
it seems react-devtools has 2 related issues:
facebook/react-devtools#223
facebook/react-devtools#214

Are you setting the border color directly on a View or using another component? If the latter you may need to update it to call processColor('#dddddd') instead.

[yelled3]

@ide yeah I was doing:

this.refs.container.setNativeProps({'borderColor': '#dddddd'});

so I should change it to?

import React from 'react-native';
import { processColor } from React;

this.refs.container.setNativeProps({'borderColor': processColor('#dddddd')});

in what other cases should I be using processColor? couldn't find it in the docs...
was this added in v0.12.0?

[brentvatne]

If that's necessary, I feel like setNativeProps or precomputeStyle (which is used by setNativeProps) should be updated to use processColor automatically. Can you let us know if that's required @yelled3?

Facing the same problem.
I'm trying to call processColor myself, but got undefined

const {processColor} = React;
console.log(processColor);

use processColor works on me

[xinthink]

Sorry, I just saw processColor exported in react-native.js of RN 0.12.0. so it should work for me either.

yes it is :-)

agreed.

@xinthink I'm using 0.12.0. Why am I still getting processColor is undefined ?

[skyline75489]

And the error is not even from my own code. It's from https://github.com/corymsmith/react-native-icons/blob/master/SMXIconImage.ios.js
