Hi Christoph,

1. Yes i have that variable.

2. Not sure because I set that variable on authentication succes, but how can i check it? 


I would like to use ((Session) session()).authenticatedUser  directly in all my components but i have customs Frameworks thats contains some of my components. And I am unable to have access to ((Session) session()).authenticatedUser in those components.

that why i am trying to bind that object to the components in framework.

I don't know if there is another way to do it.

Hi Ronald,

1. does your B.java contains a either a public property e.g.

        public UserAccount userAccount;

or a getter/setter pair, e.g.

        private UserAccount _userAccount;

        public UserAccount userAccount() {
                return this._userAccount;
        }
        public void setUserAccount(UserAccount newUserAccount) {
                this._userAccount = newUserAccount;
        }

Note, that (cum grano salis) for each binding you define in the Component API there must be a public property or a getter/setter pair with exactly the same name in the java code.

2. are you sure that the property "authenticatedUser" in your session is not null when the component is rendered?

BTW: since ((Session) session()).authenticatedUser should be accessible in every component of your app - also the subcomponents - you may use it directly in your subcomponent instead of passing it via a binding. Jm2¢.
