Error to select an item

See original GitHub issue

When I select one the first values that can I see in the list, Its works fine but when I search other item and I click, I have an error.

The error is: undefined is not an object (evaluating ‘item.value’)

app/screens/ArticleList.js:240:43 in ArticleModal
[native code]:null in find

I’m putting a console log into the function and the value arrive well.

This is my component:

<DropDownPicker
                        items = {
                            products
                        }
                        defaultValue = { article.articleName }
                        containerStyle = {{height: 40}}
                        style = {{backgroundColor: '#fafafa'}}
                        dropDownStyle = {{backgroundColor: '#fafafa'}}
                        onChangeItem = {item => onChangeSetArticle(item.value, 'articleName') }
                        searchable = { true }
                        searchablePlaceholder = "Buscar artículo..."
                        searchableError = "Artículo no encontrado"
                        placeholder = "Selecciona un artículo"
                    />

const onChangeSetArticle = (e, type) => {
            return setArticle({
                ...article, 
                [type]: e
            })
    }

Hello!

I found the problem.

I have a very long array with a lot of products and I had a “,”

const products = [ { label: ‘Uno’, value: ‘Uno’ }, { label: ‘Dos’, value: ‘Dos’ }, { label: ‘Tres’, value: ‘Tres’ }, { label: ‘Cuatro’, value: ‘Cuatro’ }, < for example… { label: ‘Cinco’, value: ‘Cinco’ } ]

Really thanks so much for helping me!!! Greetings 😃
