[Neos] Issue with content cache

[nikos]

Unfortunately I am not having much luck with this.

Just as a summary I have a Teaser content node which displays teaser text forcontent eleswhere on the site ie. targetNode.
I have defined a cache directive for the Teaser in TS with entry tags being Node_ and DescendantOf_ the targetNode (as in original posting).

I am using the standard cache setup which is a StringFrontend which uses a FileBackend for the actual cache.

The TypoScript Cache is all set up fine with all my Teaser nodes having coresponding cache files. When the target node(s) or their descendants are 
edited via the backend the Nodes are registered as requiring a change in ContentCacheFlusher->registerNodeChange and the revelant tags are added to 
flush list as expected :)

However when the Cache is flushed via ContentCacheFlusher->shutdownObject the cache file for the Teasers not removed as expected :( Seems that they 
can't be found - I have visual gone through the code in FileBackend to see that the code for saving a cache entry and seraching for it correspond and 
they look ok.

I can't really tell what is actually happening in the Filebackend, which is doing all the work, as I have not been able to debug at that level (I 
haven't had much luck with xDebug, Neos & Netbeans) but using AOP where I can I have logged what's been happening. However this doesn't work for 
FileBackend as it and all it's super classes have Proxy(false).

I am wondering if anyone has any ideas of what might be going wrong here, or suggestions as to how I could more effectively debug this area of Neos so 
I can get to the bottom of this.

Many thanks

Nikos
