Description

Per CAY-1013 I created a fix for a LOCAL_CACHE refreshing issue. Now trying to look at the bigger picture and address a related problem:

LOCAL_CACHE and multiple levels of nesting.

When we have a DataContext connected to the DataDomain, LOCAL_CACHE is what's cached at the DC level, shared - at the DD. If we have an ROP situation (CayenneContext -> DataContext -> DataDomain) or a nested DC situation (DataContext -> [DataContext]+ -> DataDomain), LOCAL_CACHE setting causes caching to occur all the way down to the last DC in a chain... This behavior is clearly wrong. Only the starting DC should cache query results.
