GUI does not show immediately show the order created

[iynixil]

Steps to reproduce:

1. Have at least 1 customer, 1 product and no orders initially. (0 orders)
2. Enter multiple valid order commands.
3. Enter valid command to add product to order.

Expected: Expected the orders created to be reflected in GUI

Actual: GUI shows a message to add a product to the orders

Rationale (includes explanation of severity):
If the app starts from a clean slate (step 1 of how to reproduce this problem), there are no orders initially. Then, when the user adds multiple orders without products in succession, they are only prompted on how to add a product to the orders. This is slightly misleading as it does not tell the user if the order has been created, and personally, I would assume that the order is created but not shown.
Then, the multiple orders created are not reflected on the GUI, which does not allow users to see how many existing orders there are.
If the user wants to add a product to any of the multiple orders, they cannot do so as the product will only be added to the latest order, and for previous orders created, while they actually do not exist, this is not shown to the user. While this way of order creation may not be the intended usage (hence Medium), it can be avoided and improved on.

Recommendation/Suggestion:
Reflect the orders in the GUI after an order
has been successfully created. Or, provide a command to show the number of existing orders and another command to show order details given the order index.
Or, state in documentation the combination of having to use order and product commands in succession to create an order, and if done otherwise, the order is not actually created.

The 'Original' Bug

[The team marked this bug as a duplicate of the following bug]

Successfully adding order does not show any order appear

It is not clear when an order has been created already since it doesn't appear until after a product is added to it

This is a bit confusing for a new user.

Their Response to the 'Original' Bug

[This is the team's response to the above 'original' bug]

This is an intended feature as we believe that we should only show an order when it had products in it, as creating an order without products might be a mistake so we delay showing the order until the user has added a product to it, since orders are meant to exist in tandem with the products they contain. So rest assured the order is there, after adding a product, the user will promptly be able to view the order.
