Hi, Let's say object A is persisted in a Voyage repository. Then object A is modified in memory. Next I want to put object A back to its state as persisted in the repository. As there is some caching in place, doing a 'ObjectA selectAll' will return the modified instance in memory, no access to the DB takes place. As understood, cache can be flushed, but it is overkill, no? Is it safe to just do: VOMongoRepostiry current cache removeObject: objectA to only flush objectA from cache?
