No, the point is that beans are not created until they are used.
So if you have <h:outputText value="#{myBean.someVariable}" />, and then
that component is rendered, the OutputTextRenderer will call getValue() on
the HtmlOutputText component. This causes #{myBean.someVariable} to be
evaluated. When faces sees that myBean is a request scope bean but does not
exist yet, it creates one. Then getSomeVariable() is called on that new
instance.
Therefore, managed beans are only created when they are asked for by the EL
resolver. So unless you actually evaluate #{myBean} or a property of myBean,
myBean will never be created. This is for performance. If there is no
request for a java bean, why create one?
So to your original question, you say your constructor is not called, my
question is if you are sure you bean is even being used. The constructor
will only be called when the bean is needed.
