Hello,

I'm running into a problem in Joomla 2.5.4 where the same content is being returned for two pages that are of the same Menu Item
Type, but use different categories when caching is enabled.

How to Reproduce:

1) Create a menu item called Home that is of Menu Item Type
"Articles >> Featured Articles".

2) Set the category for menu item Home to a category called Home.

3) Create a menu item called Contacts that is of Menu Item Type
"Articles >> Featured Articles".

4) Set the category for menu item Contacts to a category called Contacts.

5) Enable the Cache via the Global Configuration -> System page.
The problem occurs with both Progressive and Conservative
caching.

6) Visit the Home page and then the Contacts page. The Contacts
page will display the same information as the Home page instead
of displaying information related to its category.

I'm not familar with the Joomla code, but I did trace the code down to JCacheControllerView in libraries/joomla/cache/controller/view.php. The cache id being generated for both the Home and Contacts page are the same.
Modifying _makeId() slightly to include the current URL will work, but it might break something else.

Am I doing something wrong or did I hit a problem with how Joomla 2.5.4 caches views? Thanks for your help.

{
- return md5(serialize(array(JCache::makeId(), get_class($view), $method)));
+ return md5(serialize(array(JCache::makeId(), get_class($view), $method, JURI::current())));
}
}

I have found this same issue, reproduced as above. Both / either turning on Cache in Global Config or the Plugin creates this issue with Featured Articles. The Featured articles from one tab's set of categories are carried over to other tabs. Any luck with resolving this?

It looks more like a bug to me. I haven't figured out where I should report the problem on the Joomla site. The problem is that the makdeId function is not using the URI to create a unique identifier for the cached page. Modifying libraries/joomla/cache/controller/view.php does work.

Have you tried clearing the Joomla cache?

'Site' -> 'Maintenance' -> 'Clear Cache' and 'Purge Expired Cache'.

See if that helps.

Yep, I had tried clearing the cache and that didn't help. The problem is that the unique name constructed for the cached file is not unique. I added the URL to the md5 call so that the correct cached file is returned.

Do you know where can I report this problem?

Hi, I have this same problem.

Have you been able to report this? Could you provide some more information on how you were able to fix this??

Thanks

hi

do you mean "conservative" ?

using "conservative" cache the problem is in the format (colums, etc.) not in the category...

IF you apply the patch the problem is resolved - but its not resolved in 2.5.8 yet- it should be resolved in 2.5.9

Not solved yet in 2.5.9

Yes it was not resolved on my 2.5.9 yet as well.

It seems that they found another bug related to this

http://joomlacode.org/gf/project/joomla ... m_id=29250

and that this is now the correct patch to add

http://joomlacode.org/gf/download/track ... ennis.diff

All you need to do is:

Edit: /components/com_content/controller.php

Change line 66:
