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.

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
