Hi,

I am developing a small application in JSF. It is some sort of multiple choice quiz. So, each question has 5 possible answers.
It is possible that more that one answer is correct, so it has to be possible to select more that 1 answer.
To understand it, you need to know that each question belongs to a category. So, this is the structure.

CategoryDTO has a list of QuestionDTO and in this QuestionDTO there is a String[] that should contain the selectedAnswers.

Therefore I used a h:selectManyCheckbox. The page renders ok, but when I submit my answers, the list is null (I means the String[] selectedAnswers of the QuestionDTO).

This is the code of the jsp


This is the saveQuiz_action() that is called upon submitting



Does anyone have a clue what is wrong, because I can't figure it out.
I use BEA Workshop Studio 3.2.1 for development with JSDK 1.5 and for deployment I use Tomcat 5.5.20

Thank you very much.
