What are common challenges faced by JSF developers during project implementation?

JSF developers often encounter challenges related to integrating JSF with modern front-end frameworks and ensuring compatibility with legacy systems. Managing state across complex user interfaces and optimizing performance for large-scale web applications can also be demanding. Additionally, debugging and troubleshooting issues that arise from JSF's component-based lifecycle requires a solid understanding of the framework's internals. Collaborating closely with back-end and UI/UX teams is essential to deliver seamless user experiences and maintain code quality.
