I agree with you Fabio. Evict doesnt work quite as you would expect
it to from a user standpoint though. For example, I have a rental
queue that can be cached with a line items collection that is also
cached. If I evict the RentalQueue, the cached collection is left in
cache. If I evict the collection then each line item is still cached.
So to evict everything related to the rental queue, I must first evict
each line item, then the collection, then finally the queue. From the
developers point of view this a pain.
You may ask, why would i want to do something like this. Well each
line item has a version column and so does the rental queue itself. If
I get a stale object exception when updating one of the line items I
just want to evict the whole rental queue from the cache.
Seems like we should be able to make this process a little easier or
more intuitive.
