A partial order is kept in the 'TRADING' status and not reverted to 'OPEN' status even though there is a remaining balance to be filled. This prevents the order from showing up in the order book, and thus can never be fulfilled.
Note: keep in mind 2 cases: FillOrKill and Partial.
Also investigate:
If a user wants to cancel a partial offer, the verification dialog will not close when "OK" is clicked, but it will look like it is cancelled from the user that made the offer, but it will not be updated on the order page.
