ROP paginated lists must recover from server LRU query cache overflow
---------------------------------------------------------------------
Key: CAY-998
URL: https://issues.apache.org/cayenne/browse/CAY-998
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Fix For: 3.0
The following exception occurs on an attempt to read a page off the server-side
cached paginated list via ROP if the list is not found in the cache. While I do
not have a proof that DataContext MapQueryCache LRU overflow (which has a
default size of 2000 entries) is one and the only cause of this error, it is
certainly a bug... My strategy for fixing this would be storing the original
query on the server so that the list could be refetched if it is no longer in
the cache (for any reason)
