Hello, I am having this error Uncaught TypeError: onRowClick is not a function
at onClick (RepLogList.js:16)
my code looks exactly as in the Video, any though?

Edit:
I solved the issue - there was a mistake in the name of onRowClick, thank you

Hello

I followed your tutorial up to this chapter

I got the following error

<br />react-dom.development.js:67 Warning: Cannot update during an existing state transition (such as within render`). Render methods should be a pure function of props and state.

Any idea plz ?

Hey Amine

About your first error it seems like you are calling `this.setState()` inside the `render()` method, which is not allowed by React as the error describes

And about your second error, please double check the methods `componentWillUpdate()` and `componentDidUpdate()`. If you implemented those, it's likely that you're generating an infinite loop due to your logic

Cheers!

Hy MolloKhan

Thank you very much I really follow the tutorial, so at this point I have yet to define other methods

the problem was with the RepLogApp.js file

`
render() {

    const { highlightedRowId } = this.state;
    const { withHeart } = this.props;

    return (
        <RepLogs
            withHeart={withHeart}
            highlightedRowId={highlightedRowId}
            onRowClick={this.handleRowClick()}
        />
    )
}

`

it was necessary to put right onRowClick={this.handleRowClick and not with () onRowClick={this.handleRowClick()

I'm new to ReactJS so I don't understand 100% how it works yet

Thanks

Hey Amine

Sorry for my slow reply. SymfonyWorld week was crazy. When you do this onRowClick="{this.handleRowClick()}" it will execute the method and then, set its result on the property, that's why you need to pass just the reference of the method this.handleRockClick

Cheers!
