Subject [jira] Created: (OPENJPA-521) Collection ordering doesn''t work if the cache is enabled

Collection ordering doesn''t work if the cache is enabled

                 Key: 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
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.
