Reproducible in staging?: Y
Reproducible in production?: Y

If this was caught during regression testing, add the test name, ID and link from TestRail: https://expensify.testrail.io/index.php?/tests/view/5973059
Issue reported by: Applause - Internal Team

Action Performed:

1. Launch Expensify app
2. Log in to a HIGH TRAFFIC (Expensifail) account.
3. Click/ tap the + icon in a Group conversation
4. Click/tap on the "Split expense" option
5. Enter an amount into the BNP and select the Next confirmation button
6. Attempt to select only 1 participant and yourself and hit "Split expense" (there is nothing triggered when user tap on each participant, while there is split amount display on each participant in the web, user is able to adjust the amount as per desired)

Expected Result:

User should be able to select/deselect participants in the bill

Actual Result:

In Hybrid iOS, there is no indication of the split amount for each participant. When a user taps on a participant, no action is triggered, making it impossible to select or deselect participants.
However, this issue does not occur on the web. On the web version, each participant has a visible split amount, and users can adjust the amount to zero to effectively deselect a participant

Workaround:

Unknown

Proposal

Please re-state the problem that we are trying to solve in this issue.

In iOS, the split individual amount is missing.

What is the root cause of that problem?

For the split individual amount, we want to set a fixed width.

App/src/components/MoneyRequestConfirmationList.tsx

Line 653 in 1d2dda7

contentWidth={formattedTotalAmount.length * 8}

If contentWidth is present, then we limit the width with the textInputWidth, with an initial value of 0.

App/src/components/TextInput/BaseTextInput/implementation/index.native.tsx

Line 255 in 1d2dda7

!!contentWidth && StyleUtils.getWidthStyle(textInputWidth),

The measurement will be done by TextInputMeasurement.

App/src/components/TextInput/BaseTextInput/implementation/index.native.tsx

Line 461 in 1d2dda7

onSetTextInputWidth={setTextInputWidth}

However, for iOS, we noop the measurement, with the reason that iOS already supports auto grow, but TextInputMeasurement not only handles the auto grow measurement, but also the contentWidth measurement.

App/src/components/TextInput/TextInputMeasurement/index.ios.tsx

Lines 1 to 3 in 1d2dda7

	function TextInputMeasurement() {
	return null;
	}

What changes do you think we should make in order to solve the problem?

We can update the TextInputMeasurement for iOS to put back the contentWidth measurement.

function TextInputMeasurement(...) {
    const styles = useThemeStyles();

    return !!contentWidth && isPrefixCharacterPaddingCalculated && (
        <View
            style={[inputStyle as ViewStyle, styles.hiddenElementOutsideOfWindow, styles.visibilityHidden, styles.wAuto, inputPaddingLeft]}
            onLayout={(e) => {
                if (e.nativeEvent.layout.width === 0 && e.nativeEvent.layout.height === 0) {
                    return;
                }
                onSetTextInputWidth(e.nativeEvent.layout.width);
                onSetTextInputHeight(e.nativeEvent.layout.height);
            }}
        >
            <Text style={[inputStyle, {width: contentWidth}]}>
                {value ? `${value}${value.endsWith('\n') ? '\u200B' : ''}` : placeholder}
            </Text>
        </View>
    );
}

What specific scenarios should we cover in automated tests to prevent reintroducing this issue in the future?

N/A

@bernhardoj Thanks for your proposal. But I think it's not enough. Can you please share the video and make sure the following tests are passed?

1. The split amount is shown for each participant
2. When we change the total amount on the amount page, the split amount should stretch or shrink correctly
3. User should be able to select/deselect participants in the bill

[bernhardoj]

It's the same implementation we had before, so it will 100% work the same as before, including

User should be able to select/deselect participants in the bill

which never exists.

[dukenv0307]

User should be able to select/deselect participants in the bill

which never exists.

I also can't reproduce on web

However, this issue does not occur on the web. On the web version, each participant has a visible split amount, and users can adjust the amount to zero to effectively deselect a participant

@lanitochka17 Can you please check again?

Issue is still reproducible on hybrid IOS, 9.1.32-0
