Another reason why i want to do like that: My customers need an UI Interface to assign permisisons by themselves. When i told them the concept of roles and permissions, they told me:"I just want select one user and assign some permission to him, and nothing more!" I have thought about this question about one year!!!I implements this feature by HttpSession. Now seam is so good, I will never use old framework. And i hope seam has this feature so much!!!
