Hi
 
We are using Devforce 5.1.
 
We have a scenario where we have a table of the following structure:
 
TaskName <== Primary Key
Description
... + some other fields
 
 
If I delete a Task Entity with say (TaskName = 'Task1') by going myTask1.EntityAspect.Delete(), and I don't persist the change to the database (because I'm not ready to). If I then create a new Task with the same TaskName ('Task1') it gives me a duplicate entity error saying there is already a task with Task1, even though the original task is marked for deletion.
 
Why is this so? and how do I get around this problem.
 
Thanks
 
Jacob Jozwiak

DevForce does not allow two Entities in the Entity Cache to have the same Primary Key.  Otherwise, how could it distinguish one Entity from the other.
