I have a suspicion that something is wrong with the way nested ECs are currently working. The errors I see are the result of missing snapshots. The errors are very sporadic and hard to reproduce. I've managed to distill this down to a simple test case. If I drop this:

public void testNestedECs() {

try {

EOEditingContext ec = ERXEC.newEditingContext();

for(int i = 0; i < 100; i++) {

Company c = (Company) EOUtilities.createAndInsertInstance(ec, Company.ENTITY_NAME);

c.setName(UUID.randomUUID().toString());

ec.saveChanges();

EOEditingContext nested = ERXEC.newEditingContext(ec);

Company nestC = c.localInstanceIn(nested);

for(int j = 0; j < 10; j++) {

Employee e = (Employee) EOUtilities.createAndInsertInstance(nested, Employee.ENTITY_NAME);

e.setFirstName(UUID.randomUUID().toString());

e.setLastName(UUID.randomUUID().toString());

e.setManager(Boolean.FALSE);

e.addObjectToBothSidesOfRelationshipWithKey(nestC, Employee.COMPANY_KEY);

nested.saveChanges();

ec.saveChanges();

}

c.delete();

ec.saveChanges(); //Line 78

}

} catch (Exception e) {

e.printStackTrace();

Assert.fail(e.getMessage());

}

into ERXECTest.java, I get fairly reliable failures due to missing snapshots.

java.lang.IllegalStateException: recordDeleteForObject: com.webobjects.eoaccess.EODatabaseContext com.webobjects.eoaccess.EODatabaseContext@489bb457 failed to find a snapshot for EO with Global ID:_EOIntegralKeyGlobalID[Employee (java.lang.Integer)491] that has been deleted from er.extensions.eof.ERXECer.extensions.eof.ERXEC@44581ea2.

If I drop the number of loops down to 10 instead of 100, I don't see the exceptions. Does anyone see an obvious problem with my test case or perhaps have ideas about what's going wrong before I begin digging? :-)
