I'm having issues where some Entities and change tracking.  When I update the entity's data fields, the entity state remains "unchanged" rather than "modified".  I am not able to reproduce this in another solution yet.

Does anyone know what factors could result in this behavior?

Hi c63205;

An entity's state will change from "modified" to "unchanged" if you have called EntityManager.AcceptChanges, EntityManager.RejectChanges or EntityManager.SaveChanges (or SaveChangesAsync). Maybe you could check if you're calling any of these methods in places you don't intend to.

I can give you better suggestions if you could provide more information on how you're seeing this weird behavior, i.e. what kind of tests or observation that you do that led you to conclude the entity's state remains "unchanged" after an update to the data fields.

And I'm assuming you're not using DevForce POCO's correct? http://drc.ideablade.com/xwiki/bin/view/Documentation/poco

Can you do something similar to below right after you modify the field?

var newState = YourEntity.EntityAspect.EntityState.

Is newState still unchanged?
