Answer 1

Recently I have problem with injecting nested managed bean properties by @ManagedProperties too. Once injected it never changed. I did a workaround by evaluating EL in getter instead of injecting it.

Try that:

public String getUserName() {
    FacesContext context = FacesContext.getCurrentInstance();
    return (String) context.getApplication().evaluateExpressionGet(context,"#{user.userName}", String.class);
}

You can also try injecting entire user bean and get userName field from it in getter.
