Ok, that was a bug for all datasets. It's fixed in trunk now. The
behaviour was consistent with the Delphi help: if Edit is called, first
all changes are posted of when modified is false, cancelled.

So if you call Edit after Append, the Append is cancelled, and
thereafter the prior record is edited.

But when the state of the dataset is dsEdit or dsInsert, Edit should do
nothing. Also not posting/cancelling the record.

Thanks for the example.

My guess is that you also have to remove CreateTable? I'll look into it.
