Hi,

I have two projects in Eclipse: MyProject and MyProjectBusinessLogic.
MyProjectBusinessLogic is specified in Projects tab of Java Build Path
section in MyProject's Properties.

I have one unit test extending ERXTestCasa with the following code:

    public void setUp() throws Exception {
        super.setUp();
        WOApplication.primeApplication(null,
NSBundle.mainBundle().bundlePathURL(), null);
    }

    public void testCustomerValidates() {
        Customer customer = (Customer)
EOUtilities.createAndInsertInstance(editingContext(), "Customer");
        assertValidates(false, customer);
    }

Customer is an entity of model in MyProjectBusinessLogic

When I run the unit test via Eclipse Junit launcher I get the following
error and exception:

ERROR (ERXEntityClassDescription.java:321) - Entity Customer not found in
the default model group!

Administrator is also an entity in MyProjectBusinessLogic and line 34 is:

public static AdministratorClazz clazz =
(AdministratorClazz)EOEnterpriseObjectClazz.clazzForEntityNamed("Administrat
or"); Is there a solution to this problem other that removing
MyProjectBusinessLogic from Projects in Java Build Path of MyProject? There
should be since to my mind this setup is pretty common.
