What are some common challenges when implementing a modal login form in Symfony?

One common challenge when implementing a modal login form in Symfony is handling form submission via AJAX. To solve this, you can create a separate controller action to handle the form submission and return a JSON response. Another challenge is handling form validation errors and displaying them in the modal without refreshing the page. To address this, you can use JavaScript to update the modal content with the validation errors returned in the JSON response. 

// Controller action to handle form submission via AJAX
public function loginSubmit(Request $request, AuthenticationUtils $authenticationUtils)
{
    // handle form submission logic here

    // return JSON response
    return new JsonResponse(['success' => true]);
}
