Collection ordering doesn''t work if the cache is enabled
---------------------------------------------------------
Key: OPENJPA-521
URL: https://issues.apache.org/jira/browse/OPENJPA-521
Project: OpenJPA
Issue Type: Bug
Components: datacache
Affects Versions: 1.0.2, 1.0.1, 1.0.0, 0.9.7
Environment: Kodo4.1.4 with OpenJPA1.0.0
Reporter: Xiaoqin Feng
In a use case that has 2 persistence classes - parent and child. Parent and
child is one-many relationship.
Parent entity has a collection of children.
When order-by is set for collection of children and data cache is enabled,
inserting children, updating children's field value that is used by ordering
will cause collection out of order. But data cache doesn't aware this and
returned out of order collection.
If data cache is disabled, it always use SQL query with "ORDER BY" applied so
collection is returned in correct order.
Test case will be attached.
