[jira] Created: (OPENJPA-1674) OpenJPA is not differentiating
between entity types with the same key when I use table per class.
OpenJPA is not differentiating between entity types with the same key when I use table per class.
-------------------------------------------------------------------------------------------------
Key: OPENJPA-1674
URL: https://issues.apache.org/jira/browse/OPENJPA-1674
Project: OpenJPA
Issue Type: Bug
Components: sql
Affects Versions: 2.0.0
Environment: Windows 7 / CentOS 5.4, MySQL 5.1
Reporter: Christopher Davies
OpenJPA is not differentiating between entity types with the same key when I use table per class.
Here's a snippet of my ode,
(Department) es.find(Department.class, "N/A");
(PrintQueue) es.find(PrintQueue.class, "N/A");
Both Department and PrintQueue entities are based upon the same super class but I use table per class so they are in separate tables.
As you can see they both have the same key, but if I put the department line 1st the find of the print queue will generate a class cast exception trying to cast a Department to a PrintQueue. If I put the PrintQueue line 1st I will get a class cast exception trying to cast a PrintQueue to a Department. The second find doesn't generate any SQL if I have trace logging turned on so it looks to me that it is a cache issue.

It does if told to do so:
openjpa.Compatibilty=StrictIdentityValues=true
The attached test will pass with the above config.
