Overview

This report outlines recent functional improvements and debugging efforts for the AddTransaction page. The updates prioritize enhancing user experience, ensuring data integrity, and enforcing robust input validation rules.

Key Improvements

1. Success Confirmation Modal

Feature:
A modal dialog (pop-up prompt) now appears immediately upon successful transaction submission.
Purpose:

• Provides explicit feedback to users, confirming the successful completion of the operation.
• Eliminates ambiguity and strengthens user confidence in system interactions.

2. Input Validation Enhancements

a. Amount Field Validation

Rule:
Rejects form submissions if the "Amount" field contains non-numeric values (e.g., text, special characters).
Implementation:

• Real-time validation triggered on the input’s onBlur event (when the field loses focus).
• Error message: "Invalid amount: Please enter a numeric value."

b. Required Field Validation

Rule:
Halts the save operation if any mandatory field (Type, Category, Amount, Date) is left empty.
Implementation:

• Validation executed on form submission.
• Error message: "Missing required fields. Please complete all mandatory entries."

Technical Details

Tools & Technologies

• Frontend Framework: JavaFx
• Validation Logic: Implemented using JavaScript/TypeScript.
• UI Components:
  • Confirmation modal: Custom-built modal component.
  • Error indicators: Inline validation messages with red highlighting for clarity.

Resolved Debugging Issues

Issue: Previously, invalid inputs (e.g., "ten" in the Amount field) were accepted, causing backend processing errors.
Solution: Implemented regex-based numeric validation and input sanitization to filter non-numeric characters strictly.

Outcomes

User Experience

• Reduced user errors through immediate, actionable validation feedback.
• Streamlined workflow with instant success/failure notifications, improving task efficiency.

Data Integrity

• Eliminated invalid transactions caused by missing fields or incorrect data types, ensuring clean backend data processing.

Next Steps

Additional Validation Rules

• Introduce date format validation (e.g., enforce YYYY-MM-DD format for the Date field).

UI/UX Refinements

• Add subtle animation for the confirmation modal to enhance visual feedback.
• Highlight empty required fields with a red border to draw attention to missing inputs.
