GS XAP Community HibernateDataSource functionality problem


I am investigating GS XAP Community edition to be sure I can use it in my new project. I took the Order Management System example from GS web site and now playing with OMS changing different pieces of the code and configuration. So my current OMS uses HibernateDataSource as a persistency layer to MySQL test database.

Here is a description of my OMS changes and the problem I am facing. I have two domain model classes: AccountData (which is persistable) and OrderEvent (not persistable). OMS Feeder generates 100 accounts and save them in the space (which are persisted in ‘oms-accounts’ database table). After that OMS Feeder starts generating OrderEvents for existing and non-existing accounts. Everything is working fine for existing accounts but I got unexpected results for non-existing accounts.

When AccountDataDAO.isAccountFound() method is called for non-existing account userId=‘109’ I got an AccountData object where userId=‘96’. And I have the same result for all non-existing accounts. When I do ‘select * from oms_accounts’ table the record for user ‘96’ is the first line in the result table. So it looks like Hibernate (in case of the non-existing account) returns the first line from result table. A attached my remote debug screenshot which can give more information.

Has anybody experienced the same or similar problem? Any help is very much appreciated. Thanks. h4. Attachments

We are not ware for such problem. Are you having this problem with partitioned space? Are you running in LRU or ALL_IN_CACHE? Can you post a test case? Shay
