Hi Craig,
I could not receive the email from [email protected], but I saw your
response on shale user mail-archive.
Why I need to add an instance of VC as request attribute? That is good
question~{!-~}
In our web application, we have 10 VC that extends TestVC, and TestVC extends
AbstractViewController. There is a header.jsp that is included in all pages.
In this header.jsp, we need to use the information of TestVC to decide the
navigation rule among pages. So we add an instance of TestVC as request
attribute, and access it in header.jsp. we don't specify a TestVC bean in
faces-config.xml file.
We will find a way to solve the problem since this is not a bug in the
lastest version of shale framework.
Many thanks,
Luo

Hi there, I think there is a bug in Shale framework 1.0.4-SNAPSHOT(
shale-framework-20060917.zip). in the init() function of TestVC that extends
AbstractViewController, if we get the HTTPServeltRequest object from
ExternalContext, then try to add a new attribute ( an instance of TestVC) to
the request object. The TestVC is created, then destroyed, recreated,
destroyed, recreated, destroyed.....
Just out of curiousity, why are you adding an instance of TestVC as a
request attribute, when it is already there (because its a managed bean and
JSF created it for you)? The reason this is relevant is that the underlying
mechanism that fires ViewController lifecycle events is now a
ServletRequestAttributeListener (was not the case in 1.0.1, but there were
many other bugs the way it used to be handled). That means the callback
methods are fired as soon as a request attribute is added. If you add this
same instance under some other key, the callback methods will be fired again.
If you re-add it under the same key the previous registered instance will be
destroyed, then the new instance (happens to be the same bean) init'd again --
exactly as you are seeing. Craig
