Subject [jira] Commented: (JCR-1197) ItemManager cache is getting out of sync
Date Fri, 09 Nov 2007 16:06:50 GMT

Stefan Guggisberg commented on JCR-1197:
----------------------------------------

my 2 cents: 

i don't believe that this issue is related to ItemManager's cache of ItemImpl instances.

<quote from ItemManager's javadoc>
The ItemManager's responsabilities are:
...
guaranteeing that there aren't multiple instances representing the same Node or Property associated
with the same Session instance.
...
</quote from ItemManager's javadoc>

there's no need to explicitly evict cached ItemImpl instances from ItemManager's cache.
quite the contrary, doing so would violate the ItemManager's contract.

> It seems that ItemManager cache is not maintained correctly. I'm getting InvalidItemStateException:
'propertyId' has been modified externally tryin restore/checkout versionable nodes in single
thread.
> ItemState should be evicted from ItemStateManager cache when modified, it seems that
status of ItemState is changed to MODIFIED, but itemState remains in the cache.
