Summary

0033747: Performance: Images are always retrieved when the approvals are requested from the server

Description

Images are always retrieved when the approvals are requested from the server

The problem is that image data is large and has to be transferred from the server to the terminal. Large data requires network bandwidth and takes longer to be transferred.

Steps To Reproduce

In a high volume context
Create an approval for e.g.: delete receipts
Load the WebPOS
Open the developer tools, network tab
In the WebPOS, perform the approval action to provoke the approval popup to be shown
1. Verify, in the developer tools, that the images are being loaded from the server
2. Verify that in the LoginUtilsServlet, the images are being attached to the response (item.put("image", imageData);)

How to create approval:

Proposed Solution

The solution chosen should be aligned with the solution implemented in other functionalities (e.g: product images)

We should load the images after the user data has been loaded (lazy loading)
We should not load images every time the request is done (cache)
