@Resource not working when using Spring 3.x
AnnotationConfigWebApplicationContext
Hi Everyone,
I am having some issue here with @Resource in a Click Page, it seems like
the bean is not searchable nor injectable by Spring context. I suspect that
maybe it is because I am using the AnnotationConfigWebApplicationContext
instead of plain Spring XML context.
The NullPointerException was thrown when the page get instantiated. I have
attached the full exception and below are my codes that related to the
initialization of web application context.

Hi Kristian,
Click always calls onInit() in the page events processing
except following cases:
- Page#onSecurityCheck() returns false
- Ajax request (invocation of page action)
If your case is either of these,I expect the reason is not in Click.
For example, LogoutPage is not mapped to the redirect path correctly.

Hi Naoki,
Thanks for your great advice. It's worked. Actually, the reason why I put it
in the constructor is because
when I logout from the app, spring-security redirect the page to LogoutPage,
and the "onInit()" method of LogoutPage is not even executed. I have a small
logic that need the AppConfig instance to get some property to be used
before showing the index page. Any idea why is the "onInit()" is not
executed?
Thanks again for your help.
Regards,
Kristian.

Hi Kristian,
I think it can not touch AppConfig instance in the constructor of HomePage
because Spring injects AppConfig into a field after create HomePage instance.
Could you try to move code in the constructor to HomePage#onInit()?
