    Posted: 13-May-2013 at 4:21am
Working with changetracking and complex property:


            entity.Period = new Period(new DateTime(2000,01,01), new DateTime(2222,01,01));
            entity.EntityAspect.AcceptChanges();
            entity.Period = new Period(new DateTime(9000,01,01), new DateTime(9999,01,01));

            var complexProperty = entity.EntityAspect.EntityMetadata.ComplexTypeProperties.
                                                       First(c => c.PropertyInfo.Name.Equals("Period"));
          
            var currentComplexObj = complexProperty.GetValue(entity, EntityVersion.Current);
            var orginalComplexObj = complexProperty.GetValue(entity, EntityVersion.Original);

The value of the object currentComplexObj is new Period(new DateTime(9000,01,01), new DateTime(9999,01,01)) <- this is right.
The value of the object orginalComplexObj is new Period(new DateTime(9000,01,01), new DateTime(9999,01,01)) <- this is wrong.

What am I doing wrong? Where can i get the old original value from the complex property?
Sincere regards, Johannes

Hi JJanssen,

I was able to reproduce the issue here and will file a bug report.

Regards.

Hello again JJanssen,

I wanted to follow up with you and let you know that, in the meantime, there is a workaround.

Instead of using a constructor for your Complex type 
entity.Period = new Period(new DateTime(2000,01,01), new DateTime(2222,01,01));

you can assign each complex type property separately 
entity.Period.StartDate = new DateTime(2000,01,01);

entity.Period.EndDate = new DateTime(2222,01,01));

and the issue will be gone.

thanks, for the fix in den 6.1.14
 "Fixed a problem with change tracking of Complex Type properties.  [D2443]"

Now we have another problem when importing the entites of a EntityManager into another in an EntityServerSaveInterceptor. When importing entity with ComplexProperties the original value is lost.

entity11.Period = new Period(new DateTime(9000,01,01), new DateTime(9999,01,01));
entity11.EntityAspect.AcceptChanges();
entity11.Period = new Period(new DateTime(9000,01,01), new DateTime(9999,01,01));
entityManager11.AddEntity(entity11);
entityManager22.ImportEntities(entityManager11.Entities, MergeStrategy.OverwriteChanges);
var entity22 = entityManager22.Entities.First();

The changetracking information for entity11 works, but not for the entity22.

Please help us,
Johannes Janssen
