RE: [eclipselink-dev] JPA 2.0: Ordered Lists open issues


I do not believe throwing an exception when non-contiguous index values are found is an option. That would mean a developer using EclipseLink would have to wrap every collection mapping access in a try-catch block. Ultimately we need to support reading these in and writing something back out if the list is changed.

I also do not believe missing values should be interpreted as null entries in the collection.

As far as fixing the index values go we could reset them all if any changes are made or we deal with the more complex solution of figuring out values for new and changed values without a broader update to all rows.
