    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>
