IsDirty & Managed Child fields

Pawz posted on Wednesday, June 10, 2009

Hi,

I've got an odd scenario that's been happening and I'm not sure if it's by design and I'm missing something, or if I'm just missing something in my code in general.

It's the basic root + child list + child scenario, with lazy loading of the child list

Company -> TradingNames -> TradingName.

Property in company:

        public CompanyTradingNames TradingNames
        {
            get
            {
                if (!FieldManager.FieldExists(CompanyTradingNamesProperty))
                {
                    if (IsNew)
                        LoadProperty(CompanyTradingNamesProperty, CompanyTradingNames.NewTradingNames());
                    else
                        LoadProperty(CompanyTradingNamesProperty,
                                     CompanyTradingNames.GetTradingNamesFromCompanyAsParent(Id));
                }
                return GetProperty(CompanyTradingNamesProperty);
            }
        }

Company.DataPortal_Update() calls

 FieldManager.UpdateChildren(this, DM); // Passes in reference to the SQL manager object I'm using

However, this test fails:

        [Test]
        public void TestingIsDirtyOnChildObjects()
        {
            _company = _company.Save();
            Assert.IsFalse(_company.IsDirty);
            CompanyTradingName n = _company.TradingNames.AddNewTradingName();
            Assert.IsTrue(_company.IsDirty);
            n.TradingName = "test";
            //_company.Notes = "These are new notes";  //Test passes if uncommented
           
            _company = _company.Save();
            n = _company.TradingNames[0];
            Assert.IsFalse(_company.IsDirty);  // Fails here
            n.TradingName = "Testing Dirty";
            Assert.IsTrue(_company.IsDirty);

        }

If I uncomment the //_company.Notes line, the test passes. I'm not really sure what's going wrong!

If anyone has an idea I would appreciate the help.
