Is there an easy way to invalidate an object or nodes cache such that when it is next viewed the cache for it has to be rebuilt?

I have a case where im changing the attributes of some objects, which are displayed in the admin. After i store the attributes the main node view for that object doesnt update because of cache.

Is there a simple way to handle this?

Hi Paul,

If you know the node id's you can use the following function to delete the view cache. The numbers in the array are node id's.

eZContentCache::cleanup( array( 42, 1024 ) );
