I need to create a list of commandbuttons on my page, but I have some trouble with it. I pass the list from my bean through request.setAttribute and it seems to work when I get the values one at a time, but when I run through a foreach loop, they all seem to be null (And thereby being generated, and having a default value 0, "" etc., as far as I know). Any help would be greatly appreciated! In the added code, I get the correct values when i make the buttons outside of the foreach loop, but not when I run the loop itself. The List is of integer type, and should later be a java object (ran into same problem). using JSF version 2.2. Both logtest() and gotoprofile() prints the interestpointer out.
my bean has:
@ManagedBean(name="MyProfile")
@RequestScoped
And I set my variable myInterestList in my bean with:
HttpSession session = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(true);
session.setAttribute("myInterestProfileName", profileName);
