Can't select first item on Android when isNullable={false}

[ac3charland]

When on Android and using the <Picker/> component, if the isNullable prop is set to false or left as default, when the user selects the first item in the list, it doesn't trigger the onItemChange function and the value stays as the placeholder.

If you select any other item, the picker behaves correctly. Once you've done this, you can select the first item and the picker again behaves correctly.

Hello, Sorry for this late answer. Could you describe a repro? when you mount the picker, the item props is the first element of the items props array?

Hello, I currently have this issue as well. the onItemChange does not fire when you select the first item in your defined list.

Ok, just found the cause. It's a bad behavior. if "isNullable" is false and item prop is null => the first element of the list is selected but there is an issue with the placeholder not showing the label.

I'm going to fix the placeholder.

Hello, it should be good on 0.3.13 =)

@thodubois , I am having the same issue too, even in the latest version 0.3.17, here is the example code I am using in my project.

<Picker
  item={{label: "", value: ""}}
  items={[
    {label: "a", value: "a"},
    // {label: "b", value: "b"},
  ]}
  placeholder={"Please Select"}
  onItemChange={(value) => {
    // wont trigger when items have only one object
    console.log(value);
  }}
  isNullable={false}
/>

Any update here? I am having the same issue. I have to select the 2nd item and then come back to the first one in order for the form to pick up the first item value.

I am on ios.
