Hi again,

i try to create an object hierarchy in the test editing context.
the factory methods below set up the relations as required.
then i delete the root object from the ec. I want to see, that the delete 
rule "cascade" realy does a cascaded delete!
i thought, i could test the remaining content like shown below in method 
assertEditingContextRemovedInserted.

After creation there are 3 objects in ec.insertedObjects.
After deletion of "aPerson" there are 2 still objects in ec.insertedObjects.
This means, cascaded deletes are applied not earlier than on saveChanges? 

How could i test the cascaded delete correct?

TIA

Code sample that creates the hierarchy:


...

EOEditingContext ec = this.editingContext ();   // from WOUTTestCase

CMandant m = CMandant.getMandantForAlias ( this.editingContext (),
NSProperties.getProperty ( "DefaultMandant", "pappnase" ) );

CPerson c = ( CPerson ) m.creator();

CPerson aPerson = CPerson.newPersonForMandantAndPerson ( ec, m, c );

CAddress theAddress =
CAddress.newAddressForMandantAndBusinesPartnerAndPerson ( ec, m, aPerson, c 
);

CTelecom theTelecom =
CTelecom.newTelecomForMandantAndBusinesPartnerAndPerson ( ec, m, aPerson, c 
);

// ec.saveChanges ();
ec.deleteObject ( aPerson );
// ec.saveChanges ();
// all objects should be deleted via delete rule
this.assertEditingContextRemovedInserted ();

...



public void assertEditingContextRemovedInserted ()
{
    // test if content is unchanged, i.e. added eos and removed eos
->unchanged
NSSet inserted = new NSSet ( editingContext().insertedObjects () ); 
    NSSet deleted = new NSSet ( editingContext().deletedObjects () );
    NSSet remaining = inserted.setBySubtractingSet ( deleted );
    try
    {
        assertTrue ( remaining.count () == 0 );
    }
    catch ( Exception exception )
    {
        fail ( "not all inserted objects are removed : " +
exception.getMessage() );
    }
}
