RE: @ViewAccessScoped PreDestroy
Hi,
I trying to use @ViewAccessScoped beans but am not getting the expected behavior.
I notice that @PreDestroy only gets called when I navigate from a page
using a particular ViewAccessScoped bean to another page using a
different ViewAccessScoped bean.
I expected @PreDestroy to be called whenever I navigate to a different
view. i.e. if a navigate from a page with a ViewAccessScoped bean to a
page with a ApplicationScoped or WindowScoped backing bean @PreDestroy
does not get called.
Is this a bug?
I am using CODI version 0.9.5 and MYFACES 2.1.1
Thanks
Pieter

Re: @ViewAccessScoped PreDestroy
Posted by Gerhard Petracek <ge...@gmail.com>.
hi pieter,
yes - what you tried doesn't work due to restrictions by the browser. if the
server doesn't get the appropriate information, it waits for the timeout to
destroy the beans.
and thx for your question! i also added the answer to the wiki.

Hi
I was typing in the url in the browser but without the "?windowId=e77"
I suppose it is fine as the browser will remember the parameter if the
user uses the back button, otherwise the bean will just have to wait for
the timeout.
Thanks
Pieter

Re: @ViewAccessScoped PreDestroy
Posted by Mark Struberg <st...@yahoo.de>.
Just for making this clear: we do _not_ suggest to use a plain <a href...>! Please use <h:outputLink> instead (since JSF-2>.
This will render a <a href> for you but will also manage all the view params if you like, etc. You can also add <f:param> children to pass parameters without having to do some string juggling.

Re: @ViewAccessScoped PreDestroy
Posted by Gerhard Petracek <ge...@gmail.com>.
hi pieter,
to avoid side-effects you should always use such jsf components.
if you really have to use a plain link - the solution would be:
<a
href="#{facesContext.externalContext.request.contextPath}/myPage.xhtml?windowId=#{currentWindow.id}">My
Page</a>
that's for sure more verbose than the version with h:link:
<h:link value="My Page" outcome="myPage"/>
@ViewScoped:
besides some other disadvantages, that's the behaviour specified by jsf2.
codi doesn't implement this scope itself. it just provides an adapter for
cdi which delegates to the default implementation of jsf2.
so it's better to use one of the scopes which are completely implemented by
codi itself.

gerhard

Re: @ViewAccessScoped PreDestroy
Posted by Pieter Martin <pi...@gmail.com>.
Hi,
Thanks for the reply and demo.
I see the difference is that I have been navigating to the new pages via
a browser url get request.
I tried it now with a <h:link /> and then the @PreDestroy gets called.
Is it suppose to work via get request?
Thanks
Pieter

Re: @ViewAccessScoped PreDestroy
Posted by Gerhard Petracek <ge...@gmail.com>.
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

Re: @ViewAccessScoped PreDestroy
Posted by Pieter Martin <pi...@gmail.com>.
Hi,
I have tested as you mentioned but the @PreDestroy still does not get
called.
I am using the jsf application as generated with the maven archetype.
I am however running it in embedded jetty mode, i.e. view a main method.
I have a META-INF/beans.xml in the src/main/resources dir.
page1 = helloWorld.xhtml which references the WindowScoped
HelloWorldController
page2 = testViewAccessScoped.xhtml which references a ViewAccessScoped
bean - PostConstruct called
page1 = helloWorld.xhtml, ViewAccessScoped - PreDestroy not called, as
expected
page1, again = helloWorld.xhtml, ViewAccessScoped - PreDestroy not
called, expected it to be called
page3 = helloWorld2.xhtml which references the WindowScoped
HelloWorldController - PreDestroy not called, expected it to be called
page4 = testViewAccessScoped2.xhtml which references a different
ViewAccessScoped bean - PostConstruct called, PreDestroy not called
page2 = testViewAccessScoped.xhtml which references a ViewAccessScoped
bean - PostConstruct called and PreDestroy called on page4's
ViewAccessScoped bean
I can only get PreDestroy called if I navigate from a ViewAccessScoped
directly to another ViewAccessScoped page.
Using @ViewScoped I can not get PreDestroyed to be called at all.
Using @ViewScoped if I F5 on the page @PostConstruct is called everytime
and @PreDestroy never
Thanks
Pieter

Re: @ViewAccessScoped PreDestroy
Posted by Gerhard Petracek <ge...@gmail.com>.
hi pieter,
first of all welcome @ myfaces!
as long as the bean is referenced by a page - the bean will be available for
the next page. after rendering the first page which doesn't use the
view-access scoped bean it will be destroyed (that's independent of other
beans).
