App Crash Fix: Navigating Between Loaded Audits

Introduction

This document details a critical bug encountered in the application where it crashes during navigation between already loaded audits. This issue was reported by Quentin and Adrien on November 14, 2025, and requires immediate attention to ensure a smooth user experience. Understanding the root cause and implementing a robust fix is paramount for maintaining the application's stability and reliability. This article provides a comprehensive overview of the problem, the steps to reproduce it, and the necessary correction to resolve the crashing issue. By addressing this bug, we can prevent data loss, improve user satisfaction, and ensure the application functions as intended, thereby safeguarding its reputation and usability.

Problem Description

The core issue manifests as an application crash when users navigate between audits that have been previously opened within the same session, specifically after the initial page load. This crashing behavior disrupts the user workflow and can lead to frustration and potential data loss if users haven't saved their progress. The consistent nature of this bug across different navigation paths (links and browser back button) suggests a deeper problem with how the application manages or caches audit data. To fully understand the scope of this problem, it's essential to delve into the technical aspects of the application's architecture and how it handles state management. Identifying the exact component or module causing the crash is crucial for implementing an effective and targeted solution. This description sets the stage for a detailed examination of the problem and its potential causes, leading to a strategic approach for fixing the crashing issue.

Bug Reproduction Scenario

To reliably reproduce the bug, follow these steps meticulously:

1. Navigate to the Audit List: Begin by accessing the main listing of all available audits within the application.
2. Open Audit A: Select and open a specific audit, referred to as Audit A. Allow it to fully load.
3. Return to Audit List: After reviewing Audit A, navigate back to the audit list. This can be achieved either by clicking a designated link or using the browser's back button.
4. Open Audit B: From the audit list, select and open a different audit, referred to as Audit B. Ensure it also loads completely.
5. Return to Audit List Again: Similar to step 3, navigate back to the audit list after reviewing Audit B.
6. Reopen Audit A: Finally, attempt to reopen Audit A, which was previously loaded. At this point, the application is expected to crash, confirming the bug.

This precise sequence of actions consistently triggers the application crash, highlighting the underlying issue with session management or resource handling. It is imperative to follow these steps exactly to replicate the bug and verify the effectiveness of the proposed solution. This reproducible scenario provides a clear benchmark for testing and validating the fix.

Required Correction

The primary objective is to ensure seamless navigation between audits without triggering any application crashes. This requires a thorough examination of the application's architecture to identify the root cause of the problem. Several potential issues could be contributing to this behavior, including:

• Memory Leaks: The application might not be properly releasing memory when switching between audits, leading to an eventual crash due to excessive memory consumption.
• Caching Issues: Incorrect caching mechanisms could be causing conflicts when reloading previously accessed audits.
• State Management Errors: The application's state management might be flawed, resulting in corrupted or inconsistent data when navigating between audits.
• Resource Conflicts: Multiple audits might be attempting to access the same resources simultaneously, leading to conflicts and crashes.

To address this, the following steps should be taken:

1. Identify the Root Cause: Use debugging tools and code analysis to pinpoint the exact component or module causing the crash.
2. Implement Memory Management: Ensure proper memory allocation and deallocation to prevent memory leaks.
3. Refine Caching Mechanisms: Review and optimize the caching strategy to avoid conflicts and ensure data consistency.
4. Improve State Management: Implement robust state management techniques to maintain the integrity of application data.
5. Handle Resource Conflicts: Implement mechanisms to prevent or resolve resource conflicts between different audits.

By implementing these corrections, the application should be able to handle navigation between audits smoothly and reliably. Testing and validation are crucial to ensure the fix effectively resolves the crashing issue without introducing new problems. Thoroughly testing after each correction will ensure complete resolution of the problem. This rigorous approach guarantees a stable and user-friendly experience when navigating between different audits within the application. The application should function normally without crashing, enhancing the overall user experience and preventing potential data loss. Addressing these aspects thoroughly will ensure the stability and reliability of the application. The goal is to provide a seamless and error-free navigation experience for users.

Additional Considerations

Before deploying the fix to the production environment, it's essential to consider the following:

• End-to-End Tests: Ensure that end-to-end tests are executed to verify that the fix doesn't introduce any regressions or unintended side effects. These tests should cover all critical user workflows, including navigation between audits and data manipulation.
• Test Updates: If necessary, update the existing end-to-end tests to reflect the changes made to the application. This will ensure that the tests accurately validate the application's behavior after the fix is applied.
• Comprehensive Testing: Perform thorough testing in a staging environment that closely resembles the production environment. This will help identify any potential issues that might not be apparent in a development environment.

By addressing these considerations, you can minimize the risk of introducing new problems and ensure a smooth deployment process. This proactive approach will help maintain the application's stability and reliability in the production environment. Ensuring thorough testing and updates before going live is essential for stability.

By performing these steps, you are ensuring the application's functionality and reliability and safeguarding against potential issues that might arise post-deployment. This meticulous approach is critical for maintaining a high-quality user experience and preventing disruptions to the application's operation. The overall goal is to create a more stable, user-friendly, and reliable application.

Conclusion

Addressing the application crash when navigating between loaded audits is crucial for maintaining a stable and user-friendly experience. By following the outlined steps to reproduce the bug and implementing the necessary corrections, we can resolve this issue and prevent potential data loss. Remember to launch and update end-to-end tests before deploying the fix to the production environment. This ensures that the application functions as intended and provides a seamless navigation experience for users. The improvements outlined will contribute significantly to the application's overall reliability and user satisfaction, reinforcing its value and usability. It's important to prioritize ongoing testing and maintenance to prevent similar issues from arising in the future, ensuring long-term stability and performance.
