ReactJS: Warning: setState(...): Cannot update during an existing state transition

Solution 1:

Looks like you're accidentally calling the handleButtonChange method in your render method, you probably want to do onClick={() => this.handleButtonChange(false)} instead.

If you don't want to create a lambda in the onClick handler, I think you'll need to have two bound methods, one for each parameter.

In the constructor:

this.handleButtonChangeRetour = this.handleButtonChange.bind(this, true);
this.handleButtonChangeSingle = this.handleButtonChange.bind(this, false);

And in the render method:

<Button href="#" active={!this.state.singleJourney} onClick={this.handleButtonChangeSingle} >Retour</Button>
<Button href="#" active={this.state.singleJourney} onClick={this.handleButtonChangeRetour}>Single Journey</Button>

Solution 2:

I am giving a generic example for better understanding, In the following code

render(){
    return(
      <div>

        <h3>Simple Counter</h3>
        <Counter
          value={this.props.counter}
          onIncrement={this.props.increment()} <------ calling the function
          onDecrement={this.props.decrement()} <-----------
          onIncrementAsync={this.props.incrementAsync()} />
      </div>
    )
  }

When supplying props I am calling the function directly, this wold have a infinite loop execution and would give you that error, Remove the function call everything works normally.

render(){
    return(
      <div>

        <h3>Simple Counter</h3>
        <Counter
          value={this.props.counter}
          onIncrement={this.props.increment} <------ function call removed
          onDecrement={this.props.decrement} <-----------
          onIncrementAsync={this.props.incrementAsync} />
      </div>
    )
  }
