DataObject cache works incorrect !
----------------------------------
Key: CAY-596
URL: http://issues.apache.org/cayenne/browse/CAY-596
Project: Cayenne
Type: Bug
Components: Cayenne Core Library
Versions: 1.2
Environment: Windows XP, 1.4.2_06 by Sun Microsystems Inc., DB Oracle
Reporter: Paul Ponec
Priority: Critical
Data object util method:
DataObjectUtils.objectForPK(context, persistentClass, (Object) id);
returns sometimes (freqency 30% on my sample) a DataObject with an old property
value.
If I am using code:
Expression expr = ExpressionFactory.matchExp("id", id);
SelectQuery query = new SelectQuery(persistentType, expr);
List list = context.performQuery(query);
return list.size()==1 ? list.get(0) : null;
then result (all object properties) is OK always.

A selection from map.xml:
<db-entity name="CALL" schema="TEST">
<db-attribute name="id" type="NUMERIC" isPrimaryKey="true"
isMandatory="true"/>
<db-attribute name="sign" type="VARCHAR" length="1"/>
</db-entity>
<obj-entity name="Call" className="xxx.Call" dbEntityName="CALL">
<obj-attribute name="id" type="java.math.BigDecimal"
db-attribute-path="id"/>
<obj-attribute name="sign" type="java.lang.String"
db-attribute-path="sign"/>
</obj-entity>
