I am sure you know this bit of documentation about SmartCache, hence my question direclty: could you describe here the structure of your content tree (in the part affected with the problem you are describing), and show us what configuration you created in viewcache.ini ? Plus, how did you identify that the 'clearObjectViewCache(...)' method was not called ?
Let us know, Cheers,
