How to update data?

I am new with mutable data,

How to update row in this listView?

I tried to use map and than reset state… it`s not working

select(filter) {
        const dataSet = this.state.dataSet.map((obj) => {
            obj.selected = isEqual(obj, filter);
            return obj;
        });

        console.log(dataSet.toJS());
        this.setState({
            dataSet
        })
    }

dataSet updated… but listVIew… not rerender new row… how to deal with this?

@Stormsher I recommend starting over from scratch and adding one new feature at a time until it breaks again. Then you’ll know exactly what it is that causes the problem. I unfortunately can’t go on a wild goose chase for you, as much as I would like to help.

If you find a real issue or a specific problem, please post it here and I’ll do what I can to resolve it!

Excellent, you think if it works for you, it will work anywhere…

Example is braked… it`s not working normally…
