Argument 0 (NSNumber) of RCTUIManager.measureLayout must not be null

[tonyxiao]

Getting this error. Any ideas?

Src

class ScrollableLoginScreen extends React.Component {
  _scrollToInput (event, reactNode) {
  // Add a 'scroll' ref to your ScrollView
    this.refs.scroll.scrollToFocusedInput(event, reactNode)
  }

  render() {
    return (
      <KeyboardAwareScrollView ref='scroll'>
        <LoginScreen {...this.props} scrollToInput={this._scrollToInput.bind(this)} />
      </KeyboardAwareScrollView>
    )
  }
}
class LoginScreen extends React.Component {
  render() {
    const {fields, handleSubmit, submitting, error, scrollToInput, ...props} = this.props
    return (
      <View style={styles.screen}>
        <StatusBar hidden={false} />
        <View style={styles.modal}>
          <IconTextInput ref='my-input' iconName="envelope-o" placeholder='Email' style={styles.input} {...fields.email} onFocus={scrollToInput} />
          <IconTextInput iconName="lock" placeholder='Password' style={styles.input} {...fields.password} onFocus={scrollToInput} />
          <Button style={theme.BUTTON} styleDisabled={theme.BUTTON_DISABLED} containerStyle={styles.loginButton} 
            disabled={submitting} onPress={handleSubmit}>LOGIN</Button>
          {submitting && <Spinner />}
          {(!submitting && error) && <Text style={theme.TEXT_ERROR}>{error}</Text>}
        </View>
      </View>
    )
  }
}

I'm also having something like that running in a real device

The error is due to React being unable to find the node because findNodeHandle doesn't get a React node as a parameter.

If you're using RN 0.26 keep in mind that it's still not supported yet. The code must be changed from React.findNodeHandle to ReactNative.findNodeHandle.

Sorry, will release a compatible version on Monday.

I have the same issue using RN 0.25.1

[alvaromb]

@marcosinigaglia my comment is valid for RN>=0.25.

@alvaromb I seem to be having the same issue on 0.24.0

[alvaromb]

Hello!

Please debug the scrollToFocusedInput method. Try to console.log(event, reactNode) because that error usually appears then reactNode is null.

[adamrainsby]

@alvaromb Yeah that was the problem for me. Thanks

[dnish]

Are there any updates on this? I'm having the same issue on 0.25.1

[alvaromb]

@dnish there's no update. This errors appears when the reactNode sent to the scrollToFocusedInput is null. Please post your code if you need further help. Closing this issue.

Hi everybody!

Once #22 gets merged, we'll no longer need to do this kind of stuff, the component will autoscroll to the focused TextInput.

Thanks man @alvaromb , that feature is really sweet. Things got working here.
