Good to hear a fix is pending. Sad that it will be September. We have to have this working and in the hands of users by mid-August. I think we can use the EntityGroup as a work around. I set up a few unit tests and the changed event is firing properly there. I look forward to pulling that kludge out though when we can bind directly to the EntityState. Thanks.

We have two support requests open for the issues here - B1120 and F1177.  We generally have maintenance releases every 6 weeks, so the next scheduled one will be in September.  We will include the fix for the problem with not firing PropertyChanged for Entity properties, such as EntityState, in that release.

Is this something we can open a Support Ticket on and get a HotFix for? What is your plan for releasing bug fixes? Thanks.

Not firing PropertyChanged when the EntityState changes is an oversight on our part and we've opened a defect report to fix this.   The EntityManager does not currently implement INotifyPropertyChanged, but we'll also look into that.
 
Meanwhile, listening for EntityChanged events on the EntityGroup (all EntityGroups unfortunately) is one option.

I see that I can know if an Entity is dirty by checking the entityItem.EntityAspect.HasChanges property. I can also get details about whether the entity is Added or Modified by examining the entityItem.EntityAspect.EntityState property.

When I bind my UI to these properties though, they do not seem to raise the NotifyPropertyChanged event, or even seem to get updated properly at all.

The users want us to enable/disable a Save button based on whether the entity is dirty or not. When I change a property of the entity, I can manually examine the HasChanges and see it is True, but the UI does not receive notification of this change.

How should I be doing this? Thanks, Simon.
