Hello,
I have a page that performs a fetch of some objects
Of course, due to the view cache, whenever I manage those object, the page cache is not cleaned, and therefore is obsolete
=> How can I tell eZ to delete the cache of this node, whenever some objects of a specific class are modified ?
(This page/node has no relation with those objects, I use in the page the fetch('tree') template operator)

Have a look at the smartCacheClear feature of ezpublish

Yes but what rule would you put ?
I have no relation between my page and the objects shown on it
Would be nice for me to tell eZ to expire all cache of a specific node whenever a new version of an object of a specific class is created

You need to put the object ID of the node in the appropriate class section in settings/override/viewcache.ini.append.php. For example, if your node is an object of the article class:
[article] DependentClassIdentifier[]=folder DependentClassIdentifier[]=frontpage ClearCacheMethod[]=object ClearCacheMethod[]=parent ClearCacheMethod[]=siblings ClearCacheMethod[]=relating AdditionalObjectIDs[]AdditionalObjectIDs[]=xxxx
Also, you need to have smart Cache clearing enabled in settings/siteaccess/<your_admin_siteaccess>/viewcache.ini.append.php:
[ViewCacheSettings]SmartCacheClear=enabled

Thanks Daniel,
I have a last problem: the page that performs some objects, shows objects AND also drafts
And as I can see on viewcache, the rules from viewcache.ini are followed for newly published object right ?
So I guess that even if I find the good setting for viewcache, whenever I create a draft, my page won't show those ones right ?
For now, I've disabled the cache for this page, as I haven't found a better option... tell me if I'm wrong!
