Navigator not working in React Native App (Argument 0 (NSNumber)) - react-native

Question

I am trying to get navigation between views to work in React Native like so:
newUserFlow() {
this.props.navigator.push({
title: "Create Account",
component: F8InfoView,
});
}
<TopFiveButton
style={styles.button}
onPress={this.newUserFlow.bind(this)}
caption="Create Account"
/>
However, I am running into this error on click:
ExceptionsManager.js:75 Argument 0 (NSNumber) of RCTNavigatorManager.requestSchedulingJavaScriptNavigation must not be null
This worked previously, but something seems to have changed. What could be the issue?
The debugger references this in the exceptions manageR:
// Flow doesn't like it when you set arbitrary values on a global object
(console: any)._errorOriginal = console.error.bind(console);
am I breaking something in flow?
Edit
index.ios.js looks like this:
class nomad extends Component {
render() {
return (
<NavigatorIOS
style={styles.container}
initialRoute={{
title: 'Nomad',
component: LoginScreen
}} />
);
}
};
then in LoginScreen:
class LoginScreen extends React.Component {
newUserFlow() {
this.props.navigator.push({
title: "Create Account",
component: F8InfoView,
// passProps: {userInfo: this.props.userInfo}
})
}
render() {
return (
<F8Button
style={styles.button}
onPress={this.newUserFlow.bind(this)}
caption="Create Account"
/>
);
}
}
Clicking the button gives me the error.

Answer 1

Which version are you using for react ? Are you sure to be on the last stable version ? I ask you that because in ExceptionsManager.js, I cannot see "NSNumber" on line 75...
Let me underline that this question is very similar... so have you tried to put
navigator.push(routes[1]);
inside the onPress prop. ?
something like:
<F8Button onPress={
() => { if (route.index === 0){
navigator.push(routes[1]);
} else {
navigator.pop();
}
}
...
...
To conclude you may also have a closer look at https://facebook.github.io/react-native/docs/navigator.html

Hope this solution helps you a bit
Problems which might have occured
The problem was that once you execute the onPressevent, the i index is beyond bounds so the node can't be found.
Something tells me this happened because you were trying to access a ref that is null because you put the dropdown list in the renderScene function of a navigator. I had the exact same problem.
Please consider posting your code or debugging the findNodeHandle result, because this error is produced once you send null as a node.
The error may br due to React being unable to find the node because findNodeHandle doesn't get a React node as a parameter.
It may be the problem that you are sending a null node to the event. Try to debug what you're getting in the findNodeHandle function.
Solutions
You have to change all the refs to this.refs.navigator.refs['any reference made in your code'] etc.
Don't forget to give the actual navigator a ref
<Navigator
ref='navigator'
