Is there a configuration parameter to set this? dmoshal David Moshal You can set cascade delete using annotations (see also the Orphan Removal section). JDO defines similar annotations , and both JPA and JDO support this setting also in XML files, but no additional parameters exist in ObjectDB

Right, that fix to 2.4.1_02 got us past the previous issue. Now I'm not sure whether this next issue is our annotations , or another issue with objectdb. I have added some more classes to the unit test. They are used by AbstractContactDetail. On line 372 of the attached test, AbstractContactDetail

"is not null"-queries are not working correctly for indexed fields. Following SSCCE creates 1000 entities. A null value is assigned to an indexed field for every second entity. When doing count-queries at the end, wrong results are fetched. import java.io.Serializable; import javax.jdo. annotations

I think it would be revolutionary if it were possible to persist any Java object, not just the standard SQL-based objects. Perhaps introducing an annotation will allow for this, something like @BasicType. The ability to store the state of an entire application would be a new innovative approach
