[eclipselink-dev] Minutes: Functional Discussion - Ordered Lists 
Minutes:

Open Issues: 

1.3.2.1 Non Contiguous Index values 
 Resolution:
  include the expected index in the where clause.  If the update fails, assume that the list is non-contiguous.  Re-index the list.

1.3.2.2 Indexing new elements in un-instantiated IndirectLists 
 Resolution: Don't support un-instantiated IndirectLists with Ordered List.

1.3.2.3 OrderColumn table 
 Resolution: 
  One to Many: support OrderColumn on any Target table
  Join Table: only support OrderColumn on Join Table
  Throw an exception if any other table is specified.

1.3.2.4 Duplicate support 
 Resolution: 
  Looking into Duplicates now.
  Will determine impact of supporting Duplicates as further prototyping is done.
  Duplicates with Private Owned an issue.

1.3.2.5 "Two-way" order support 
 Employee.projects and Projects.employees; say add ORDER_EMP and ORDER_PROJ fields to the join table? 
 Resolution: 
  We are not at this time supporting a different ordering on 2 mappings sharing the same join table (one being read only).

1.3.2.6 Constraints in the DB - is that possible? 
 Resolution:
  Log a Doc Bug: can't make index column part of the PK.

1.3.2.7 Target optimistic locking
 Resolution:
  Only uni-directional, use the flags that already exist on the Mapping.
  Move the flags to OneToMany.

I propose that we have a dicussion on the functional direction of Ordered Lists.

A doc with open issues is here:
