“Instantiation of new objects and access to static classes or parameters is forbidden” error with th:action
I’m working on a Spring Boot application using Thymeleaf for the view layer. In one of my templates, I need to create a form for updating a book. However, I’m encountering the following error when rendering the template:
Convert textarea input separated by comma’s to List
I have a form and in there I got a textarea where materials should be separated by a comma.
