Re: Struts2 (caching, valuestack, etc...) problem
Dave is right: daos and services are usually singletone, it looks like you
defined the result list as field and not like the return of a method
(sharing fields among method invocations also arises concurrency issues).

Re: Struts2 (caching, valuestack, etc...) problem
In general a DAO *would* be a singleton, though.

Re: Struts2 (caching, valuestack, etc...) problem
Just thought it would be good idea to update everyone here, I finally figured
it out what was my problem. I was using spring in my DAO with @Service and
@Autowired annotations. Apparantely, these annotation are singleton by default.
I added @Scope("prototype") and everything works as expected. Thanks Maurizio
and Chris for your help.

Are you using spring plugin?
Looks like you are using a previous initialized instance of your action
class.
If yes, ensure that the scope is prototype and not the default one (which
is singletone)

I added the scope to prototype in my spring beans definitions. However, the problem persisting. I deleted my browser history and ran the application.

Re: Struts2 (caching, valuestack, etc...) problem
You might be right. I am using spring-plugin and my beans definition are not set to any scope. I will try to use prototype. Thanks a lot, let me make the changes and I will let you know my findings.

Re: Struts2 (caching, valuestack, etc...) problem
You have to find the cache first. It could be cached by the browser, the server, the container or your application. If every request is making it through to your action, then it's most likely code in your application that's reusing something from the last request. If some of the requests don't trigger your action, the problem is in one of the other three layers and you'll have to do some investigation to figure out which (something like TamperData Plug-in for FireFox might help) (*Chris*) On Mon, Jun 4, 2012 at 11:37 AM, Omar Ngarigari wrote: > I am running the application on jboss6 app server.

Re: Struts2 (caching, valuestack, etc...) problem
I am running the application on jboss6 app server. I don't see anything on server console. I have debugged the app, I can see that the new input quarter date is returned when the request is made on the app log file. I tried your suggestions by adding ?something=kskdsds at the end of the url, but I got no record found. Can you show me how to clean a cache?

If it is just showing you the cached page, try appending some nonsense parameter to the end of the URL (i.e. ?dummy=aalskdjfkal).

Re: Struts2 (caching, valuestack, etc...) problem
Are you watching your server console? Are you sure it's actually making the request and not displaying the cached page. If it is just showing you the cached page, try appending some nonsense parameter to the end of the URL (i.e. ?dummy=aalskdjfkal). Otherwise, you'll have to look into your action processing, you must be retrieving something from a cache somewhere.
