@mountiny @luacmartins Just sharing my thoughts for this.

It looks like this is regression from this PR #16919 Which modified src/pages/iou/MoneyRequestModal.js line 116 from
this const [previousStepIndex, setPreviousStepIndex] = useState(0); to
this const [previousStepIndex, setPreviousStepIndex] = useState(-1);

So this the root cause of this problem.

If we set previousStepIndex default value to 0 it will solve the problem. I tested it. Thank you.

mountiny · 2023-04-20T20:59:28Z

Yeah this is a valid problem

Proposal

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

Whenever go to send/request money flow, it will show sliding animation two times i.e. first time when initial loader shows, and thereafter when transition end.

What is the root cause of that problem?

We can see at line 375 it shows <FullScreenLoadingIndicator /> until didScreenTransitionEnd thereafter once transition end it will render content based on the 376 and <AnimatedStep> component load based on the steps and using direction.

App/src/pages/iou/MoneyRequestModal.js

Lines 375 to 380 in 1cd304c

    
           {!didScreenTransitionEnd && <FullScreenLoadingIndicator />} 
        
           {didScreenTransitionEnd && ( 
        
               <> 
        
                   {currentStep === Steps.MoneyRequestAmount && ( 
        
                       <AnimatedStep 
        
                           direction={direction}

During component load here is the state for previousStepIndex and currentStepIndex

App/src/pages/iou/MoneyRequestModal.js

Lines 116 to 117 in 1cd304c

    
           const [previousStepIndex, setPreviousStepIndex] = useState(-1); 
        
           const [currentStepIndex, setCurrentStepIndex] = useState(0);

Directions are decided based on the functions below:

App/src/pages/iou/MoneyRequestModal.js

Lines 166 to 189 in 1cd304c

    
           const direction = useMemo(() => { 
        
               // If we're going to the "amount" step from the "confirm" step, push it in and pop it out like we're moving 
        
               // forward instead of backwards. 
        
               const amountIndex = _.indexOf(steps, Steps.MoneyRequestAmount); 
        
               const confirmIndex = _.indexOf(steps, Steps.MoneyRequestConfirm); 
        
               if (previousStepIndex === confirmIndex && currentStepIndex === amountIndex) { 
        
                   return 'in'; 
        
               } 
        
               if (previousStepIndex === amountIndex && currentStepIndex === confirmIndex) { 
        
                   return 'out'; 
        
               } 
        
               if (previousStepIndex < currentStepIndex) { 
        
                   return 'in'; 
        
               } 
        
               if (previousStepIndex > currentStepIndex) { 
        
                   return 'out'; 
        
               } 
        
               // Doesn't animate the step when first opening the modal 
        
               if (previousStepIndex === currentStepIndex) { 
        
                   return null; 
        
               } 
        
           }, [previousStepIndex, currentStepIndex, steps]);

So here during component load it will trigger the third condition i.e. line 178 as shown in code above. So this is the root cause of the problem.

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

We can to set previousStepIndex to 0 as show below, it will solve the issue.

// const [previousStepIndex, setPreviousStepIndex] = useState(-1); //  Old
const [previousStepIndex, setPreviousStepIndex] = useState(0);  // Updated

This will solve the issue as shown in result video.

What alternative solutions did you explore? (Optional)

We can keep previousStepIndex and currentStepIndex value as it and add if condition at position shown below, and remove if from last as shown in code below:

const [previousStepIndex, setPreviousStepIndex] = useState(-1);
const [currentStepIndex, setCurrentStepIndex] = useState(0);

const direction = useMemo(() => {
    ...
    if (previousStepIndex === amountIndex && currentStepIndex === confirmIndex) {
        return 'out';
    }
    if (previousStepIndex === -1 && currentStepIndex === 0) { // *** Add if condition here ***
        return null;
    }
    ...
    // Doesn't animate the step when first opening the modal
    // if (previousStepIndex === currentStepIndex) { // *** Remove this if condition as it is not need ***
    //     return null;
    // }
}, [previousStepIndex, currentStepIndex, steps]);

The confirmation page animation is also wrong it slides from the right. That should only be the behavior when editing a field.

@chiragxarora mind applying to the Upwork job for eventual reporting payment? Thank you!

chiragxarora · 2023-04-20T23:12:37Z

Hi @MitchExpensify
Is the job link same for both reporter and solver?
Do I have to write anything specific in the proposal?
This is my first one here, have no idea

MitchExpensify · 2023-04-20T23:13:55Z

Nope just apply so I know your Upwork profile, easy! @chiragxarora 👍

chiragxarora · 2023-04-20T23:18:12Z

Done!

s77rt · 2023-04-21T01:56:24Z

@PrashantMangukiya Thanks for the proposal. Your RCA makes sense. But I think we need to understand why such change was required.

@yuwenmemon Was there any reason to change the default previousStepIndex value from 0 to -1. Or was that done just to be "correct" and if so any reason why we didn't use null instead of -1.

s77rt · 2023-04-21T01:58:39Z

@luacmartins ~~I'm not sure I understood what you are referring to exactly, can you please attach a video and edit the OP if you think we should handle that too.~~
Edit: I got it, but need to initiate the process from the chat. Please update issue body..

dukenv0307 · 2023-04-21T09:06:55Z

Proposal

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

There're 2 problems here regarding the animation:

Double sliding animation on Send/Request Money
The confirmation page animation is wrong when navigation from the MoneyRequestAmount to the MoneyRequestConfirm page (mentioned here)

What is the root cause of that problem?

Here

App/src/pages/iou/MoneyRequestModal.js

Line 178 in 214658e

if (previousStepIndex < currentStepIndex) {

where we set animation direction to in when previousStepIndex < currentStepIndex, the condition is also true when the previousStepIndex is -1 and currentStepIndex is 0 which is the initial state of the page, causing the double animation.
Here https://github.com/Expensify/App/blob/214658eca48517fc3c2d087f569187ddec173ee7/src/pages/iou/MoneyRequestModal.js#L171-174 and here

App/src/pages/iou/MoneyRequestModal.js

Line 174 in 214658e

if (previousStepIndex === amountIndex && currentStepIndex === confirmIndex) {

we're using custom condition to handle the case of navigation from the MoneyRequestConfirm page to the MoneyRequestAmount page when editing the amount. So basically since the step of MoneyRequestAmount is 0, step of MoneyRequestConfirm is 1, if we don't have this condition, when we navigate from the confirm page to the amount page to try to edit the amount, it will show backwards animation. However that condition breaks the animation of forward navigation from amount page to confirm page initially (not editing).

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

The direction is only relevant if we go from 1 page to another page, meaning we have previousStepIndex >= 0 ( previousStepIndex = -1 means that there's no previous page)
So we need to check if previousStepIndex < 0 in the beginning of

App/src/pages/iou/MoneyRequestModal.js

Line 166 in 214658e

const direction = useMemo(() => {

.

If true, it will return null so there's no animation, and the outdated condition here

App/src/pages/iou/MoneyRequestModal.js

Line 186 in 214658e

if (previousStepIndex === currentStepIndex) {

can be removed since it's not possible for previousStepIndex to be equal to currentStepIndex.

We cannot set previousStepIndex to 0 initially because that will break the amount editing flow. As we can see here

App/src/pages/iou/MoneyRequestModal.js

Line 234 in 214658e

if (currentStepIndex <= 0 && previousStepIndex < 0) {

, previousStepIndex -1 is relied on in the navigation logic.

To fix this we need to rethink how we're handling the edit amount flow

Currently what we do is:

Both the set amount and edit amount are step 0
If we navigate from confirm page to amount page to edit the amount, by right we're moving forward in the navigation but in code we're actually navigating back to step 0. And then we add a number of non-straight-forward conditions like here and here to show the correct animation & navigation. It can be interpreted as "navigating from step 1 to step 0 but please use forward rather than backward animation", ... which is error prone.

I suspect the reason for that is that we're using the same UI for both steps.

We need to change to:

edit amount and set amount are 2 separate steps (edit amount will be a new step after confirm page )
In

App/src/pages/iou/MoneyRequestModal.js

Line 378 in 214658e

{currentStep === Steps.MoneyRequestAmount && (

we'll show the same UI for both the edit amount and set amount steps
Then we can remove all the workaround-ish manipulation for the edit amount case, for example here and here, since when navigating from the confirm page to edit amount page, it's regular forward navigation so it will work with regular animation direction and navigation logic
In here if it's edit amount step we'll go back, if it's set amount step we'll go to next page.

What alternative solutions did you explore? (Optional)

NA

Looks like something related to react-navigation may have been mentioned in this issue discussion.

As a reminder, please make sure that all proposals are not workarounds and that any and all attempt to fix the issue holistically have been made before proceeding with a solution. Proposals to change our DeprecatedCustomActions.js files should not be accepted.

Feel free to drop a note in #expensify-open-source with any questions.

luacmartins · 2023-04-21T13:18:01Z

@s77rt here are the steps to reproduce and a video. If we agree that it's an issue, I can edit the OP to include this.

Request money from the global create
Notice that the confirmation page slides from right to left (0:06 in the video), which is correct
Now, request money from within a chat
Notice that the confirmation page slides from left to right (0:11 in the video), which is wrong
