Bug Description

---

1. Summary

When the user has a text input on the left and an interactive element (Eg. button) on the right, the cursor position selection on the text input when returning the focus from the right element will shift one to the left instead of remaining at the end.

Eg. “InputText|” → focus on right element → focus back to text input→ “InputTex|t” → focus on right element → focus back to text input → “InputTe|xt”

The prop for selection could be a potential workaround but another issue occurs if the user opens up the virtual keyboard and starts adding inputs. It’ll stay at the set position (eg. position 3 instead of updating to 4, 5… and so on). It’ll just keep adding text from that position instead of appending it to the end. We can’t also unset this selection prop by assigning it undefined.

2. Steps to Reproduce

1. Have a TextInput component on the left side and a Button component on the right side
2. Add text to the TextInput so that the cursor position is at the end
3. Focus on the right button
4. Focus back on the TextInput by pressing left
5. Repeat a few times

3. Observed Behavior

Explain what actually happened, noting any discrepancies or malfunctions.

The cursor/selection shifts one left each time it returns from the right element.

4. Expected Behavior

Describe what you expected the SDK to do under normal operation.

The cursor/selection should remain at the end (or the previous position when it was unfocused) when being focused from another element.

4.a Possible Root Cause & Temporary Workaround

Fill out anything you have tried. If you don’t know, N/A is acceptable

Tried using the `selection` property to set the start & end. But this position cannot be unset.

Hi @John_Zhang,

Thank you for the detailed bug report on the TextInput keyboard focus issue.

Our team is investigating this issue and will provide an update as soon as we have more information.

Thanks for helping us improve the Vega platform.

Warm regards,
Aishwarya

We have similar issue. On Android, it can be fixed by passing caretHidden={!Keyboard.isVisible()} But on Vega, it doesn’t work the same way. Vega simply ignores caretHidden value.

Hi @Liudmyla,

Can you please share the minimal reproducible code snippet with us and any other details that will help us debug this?

Thanks,
Rohit

It’s pretty simple: TextInput to the right and some Pressable element to the left.

<View style={{flexDirection: 'row'}}>
  <Button
    label={i18n.globalButtonBack()}
    onPress={navigateBackOrHome}
  />
  <TextInput
     style={styles.inputField}
     value={inputText}
     onChangeText={setInputText}
     onSubmitEditing={handleOnSubmitEditing}
     caretHidden={!isKeyboardVisible} // is ignored
  />
<View>

Pressing left each time from the TextInput moves focus to the Button, but also moves cursor to the previous symbol.

Hi @amen ,

I believe @Liudmyla shared a pretty similar snippet as what we have.

<View style={{flexDirection: ‘row’}}>
    <TextInputstyle={{width: 500}} value={inputText} onChangeText={setInputText}/>
    <Button />
</View>

Hey, I also noticed that it doesn’t support cursorColor and setSelection method, which could help fixing this issue.

[Amz_Rsk]

Hi @Liudmyla , @John_Zhang ,

Thanks for sharing the info.

Our team is still looking into this. We will get back once we have an update.

Hi @John_Zhang , @Liudmyla ,

Unfortunately, we are unable to reproduce the issue with the shared code snippet.
Could you please share the simple vpkg or app.tsx with your Amazon POC please?

Thanks
Rohit

Hi @Amz_Rsk , I have provided a video and code sample to @satish_amazon .
