    Hi all

    Using Cayenne 1.2.2, jdk5.

    In the modeler under cache configuration the "use shared cache" is
    disabled. This value I want to override programatically for example:

       boolean useSharedCache = true;
       DataContext context = DataContext.createDataContext(useSharedCache);
       DataObjectUtils.objectForPK(context, Employee.class, 200);

    This throws a nullpointer. Stack trace below.

    Is this valid use of the API?

    If I enable the "use shared cache" in the modeler this works fine, so
    its not a big issue.

    Stacktrace:

    Exception in thread "main" java.lang.NullPointerException
    org.objectstyle.cayenne.access.DataDomainQueryAction.interceptOIDQuery(DataDomainQueryAction.java:166)
