Subject Re: @ViewAccessScoped PreDestroy
Date Fri, 24 Jun 2011 17:01:28 GMT
hi pieter,

based on the archetype i created a demo [1].
i just added a view-access-scoped bean and accessed it on the second page.
in the @PostConstruct callback a message gets added which you can see on the
page.
the @PreDestroy callback writes the message to the console because the bean
gets destroyed >after< the rendering process (if it wasn't accessed by the
new page) - so you won't see a message on the page (if you would add one
like in the @PostConstruct callback).

you can start the demo e.g. with:
mvn clean jetty:run-exploded -PjettyConfig

regards,
gerhard
