[jboss-jira] [JBoss JIRA] Commented: (JBPORTAL-1325) ConsumerCacheInterceptor : should not use the cache just after login

[Antoine Herzog (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBPORTAL-1325?page=comments#action_12371905 ] 
            
Antoine Herzog commented on JBPORTAL-1325:
------------------------------------------


This is not an issue..... (I did this jira in march when exploring things about cache... did not see the thing explained since by Julien).

Should be closed. 
(see comments yet above).

about checking : this was asked by Julien, but I think it was "just in case..."
I don't think it is usefull.

not yet using the cache with 2.6 (don't want to add this while starting some ajax stuff).... 

if I see something, I'll reopen this... but sure it won't be necessary.

>          Components: Portal Core
>         Environment: jbp 2.4.0
>            Reporter: Antoine Herzog

>             Fix For: 2.8 Final, 2.6.2 Final

> Use case : 
>  - user come to the site. 
>  - Portlet show views for unchecked user. These views are put in the cache.
>  - user log in, let's say as admin
>  - the cached views still show the previous things, not taking into account the change of authorizations
>  - the user can't see the proper things
> usual needs :
>  - for I18n portals : change of locale when user log in. all the portlets must do the change, not depending on cache
>  - for admin or special roles features in the  portlet views
>  - for modes depending on roles (see forum post)
> In the default portal, there are no use of cache. so all these use cases are fullfiled.
> to reproduce the problem : 
>  - put some cache on the user portlet (great feature for prod), the user portlet window may not update after logging.
> resolution :
> in the ConsumerCacheInterceptor
> the CacheKey do not take into account the login state.
> see : public CacheKey(StateString navigationalState, WindowState windowState, Mode mode)
> so store the user name (or "unchecked") in the CacheEntry.
> put the parameter "userOfFragment" in the CacheKey.
> when retrieving the CacheEntry, compare the currentUser and the userOfFragment, and don't use the cache if different.
> just to see : can we have access to the logued user in this interceptor ? (that, i don't know)
