I found a solution but I want to know how bad it is?
in my Session's awake, I am creating an EC and doing a fetch of all my Projects:
EOEditingContext theComparisonEC = ERXEC.newEditingContext();
NSArray<Project> compArray = Project.fetchAllProjects(theComparisonEC);
ERXThreadStorage.takeValueForKey(compArray, "theCompArray");
then in the willUpdate() method, I iterate over the array and find the primaryKey of the current Project.
Now I have my before and after.
the question is, how bad is this. I can not imaging that this database will ever get over a few thousand rows. Meaning if it is still in use in 10 years, there will be 5k rows.
