Order of Query Execution in Workbook

Question

I have a workbook with 3 queries.  I have some macro code that moves results around and does formatting.  The code is dependent on the order in which the queries are executed.  I had assumed that the queries are executed in the order they are listed as data providers.
For most of my users, the workbook works fine.  But for some, the queries execute in a different order.  Is there some way to force the order of query execution?
Thanks,

TopLink uses a deferred transaction model implemented through its UnitOfWork. This means all changes (creation, modify/ removal) are tracked and during the transaction commit phase we perform these operations ordered based on your referential integrity rules (FK constraints).
If you are using TopLink Essentials (JPA) you have the option to issue flush on your entity-manager after the persist call to force the insert to occur prior to your next read.
In Oracle TopLink the only way to do this is to use a DatabaseSession which offers additional calls controlling the transaction directly as well as support insert/update/remove operations without the UnitOfWork. This approach supports these additional calls because it uses a single connection and does not have a multi-client shared cache. This is much closer to a pure data access style versus the rich multi-client persistence infrastructure most commonly used.
