Tell us what’s happening:
the code passes all tests but in console i get the error e.onNext is not a funtion when i press update button.
If i remove all the lifecycle the button works.
If i keep the one provided(componentWillUpdate) or any other combination with the other two i get the same error.
Your code so far
class Dialog extends React.Component {
constructor(props) {
super(props);
}
componentWillUpdate() {
console.log('Component is about to update...');
}
// change code below this line
componentWillReceiveProps(nextProps) {
console.log(this.props + '-' + nextProps)
}
componentDidUpdate() {
console.log('Component did update')
}
// change code above this line
render() {
return <h1>{this.props.message}</h1>
}
};
class Controller extends React.Component {
constructor(props) {
super(props);
this.state = {
message: 'First Message'
};
this.changeMessage = this.changeMessage.bind(this);
}
changeMessage() {
this.setState({
message: 'Second Message'
});
}
render() {
return (
<div>
<button onClick={this.changeMessage}>Update</button>
<Dialog message={this.state.message} />
</div>
);
}
};
