BUG: Incorrect URL State Handling When Switching Between Tabs on Encounter Patient Page

As healthcare professionals navigate through the Encounter Patient Page, they often rely on the correct URL state handling to ensure seamless transitions between tabs. However, a critical bug has been identified, affecting the URL structure when switching between tabs, particularly when navigating between parallel tabs and sub-tabs. In this article, we will delve into the details of this bug, its expected behavior, and the necessary steps to reproduce it.

When navigating between parallel tabs (e.g., Files → Plots), the URL updates correctly (e.g., /files → /plots). However, when clicking on an additional sub-tab inside Files, the URL changes to /files/subtab, and switching back to Plots (or other tab) results in a different URL (/files/plots) instead of the expected /plots. This incorrect URL structure causes navigation breaks or inconsistencies, hindering the user experience.

To reproduce this behavior, follow these steps:

Step 1: Open the Encounters page

Navigate to the Encounters page, where you can select a patient to view their details.

Step 2: Select a patient

Choose a patient from the list to view their encounter details.

Step 3: Navigate to the Files tab

Click on the Files tab to access the patient's files.

Step 4: Click on one of the additional navigation buttons

Inside the Files tab, there are two additional navigation buttons. Click on one of these buttons to access the sub-tab.

Step 5: Observe the URL change and navigation inconsistencies

After clicking on the sub-tab, the URL changes to /files/subtab. Now, if you click on outside tabs parallel to the File tab, navigation breaks or becomes inconsistent due to the incorrect URL structure.

The expected behavior is as follows:

Clicking on Files should always set the URL to /files.
Clicking on Plots should always set the URL to /plots, regardless of previous sub-tabs.
Clicking inside Files (on sub-tabs) should modify only the sub-state (/files/subtab), but it should reset properly when switching back to a parallel tab.

To resolve this bug, we need to implement a solution that ensures correct URL state handling when switching between tabs, particularly when navigating between parallel tabs and sub-tabs. Here's a proposed solution:

Solution:

Implement a robust URL state handling mechanism: Develop a mechanism that accurately updates the URL when switching between tabs, taking into account the sub-tab state.
Use a consistent URL structure: Ensure that the URL structure remains consistent, even when navigating between parallel tabs and sub-tabs.
Reset sub-tab state properly: When switching back to a parallel tab, reset the sub-tab state properly to avoid navigation inconsistencies.

Timeline:

Day 1-3: Implement the robust URL state handling mechanism and consistent URL structure.
Day 4-6: Test and refine the solution to ensure proper sub-tab state resetting.
Day 7: Submit a completed Pull Request with the solution.

The bug identified in this article affects the URL state handling when switching between tabs on the Encounter Patient Page. To resolve this issue, we need to implement a solution that ensures correct URL state handling, consistent URL structure, and proper sub-tab state resetting.
