> UIXCollection in the preRowDataChange saves the current stamp state. The problem is that the code does not check to see if there is a current stamp. The result, is child components may not correctly function if they expect to be inside a valid stamp. What happens is that when the collection first sets its row key/index, the stamp state is saved for index -1 (row key null). Children components that assume that the collection is processing a stamp may error out. There should be no reason why the stamp state is being saved when there is no stamp.
> I have come across user's of our code where they are getting exceptions in their code as a result.
