hi pieter,


no - that's specified by cdi itself. please don't place code in the
constructor (use @PostConstruct instead).

Hi,

I have a the following producer method

    @Named("contextRoot")
    @Produces
    @ConversationScoped
    @ContextRoot
    public CmApplication getContextRoot() {
        return (CmApplication) db.getCompositeRoots().get(0);
    }

and I reference it in jsf<h:inputText id="rootLabel"
value="#{contextRoot.name}" />

When I navigate to the page before the producer method gets called the
object is instantiated by owb/codi. Is this avoidable?

The producer method is called afterwards.
