UseSharedCache programatic override failure

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

Hi Bob,

 From a quick glance looks like a bug. Could you please open a bug
