I'm still experiencing this. I validate the topology every day and am still receiving the same 70+errors that I've previously marked as exceptions. Has anyone else been experiencing this?
I don't think Arc Map remembers the exceptions. It has been a while, but my recollection is if you validate again, the previous exceptions are lost and you have to redo the exceptions. A little frustrating.
Nice to know that it does remember. I'll have to confirm that for myself next time I have to use it. I just recall wanting that functionality for the topology tools and not seeming to be able to get it; that is, it seemed like whenever I re-validated that it would re-highlight those that I had marked as exceptions.
