Andrus Adamchik updated CAY-998:
--------------------------------
Description:
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 along the lines of
passing the original query on every page request, so that the list could be
refetched if it is no longer in the cache (for any reason)
[java] org.apache.cayenne.CayenneRuntimeException: [v.3.0-SNAPSHOT Jan 23 2008
