React. Fetch data in reaction select page

    Currently almost all of our components implement componentWillMount
    to trigger some operation in reaction to select page:
    
    Example:
        
    componentWillMount() {
     //  This method runs when the component is first added to the page 
       let startDateIndex = parseInt(this.props.match.params.startDateIndex) || 0;
       this.props.requestTaskItems(startDateIndex);
    }
    
    My Solution: 
    
        componentWillMount() {
       // Now:  This method runs when the component run 
       // Note that the above example is very simple, startDateIndex is unique all time
        var startDateIndex = new Date().getUTCMilliseconds(); 
        this.props.requestTaskItems(startDateIndex);
        this.updateDimensions();
    }
