I've been fighting this and I know it must be something I'm doing, but I can't seem to figure out what's causing it. I have a business object that has several date fields. Some of the date fields indicate a start date and an end date.



In the business object's CheckRulesOnCurrentRow event, I have a rule that makes sure the start date doesn't occur after the end date. When I save a record, it correctly makes this check and saves the data if I get it right the first time. If I set the start date after the end date, it adds a broken rule and lets the user correct the problem.



I set the start date earlier, and save. I get the same message and the bound control is reset to the same later value. I keep making the change and it always switches back to the old value. The only thing I can do is click my cancel button to undo everything and start from scratch.



So far, I've tried...



... checking my code and I don't have a RejectChanges() or Refresh() call anywhere in the save process. The Undo() is only called from the Undo/Cancel process.



... Adding this.BrokenRules.Clear() to the beginning of the CheckBusinessRulesOnCurrentRow event for the business object.



Anything else I might try? Any ideas?
