If an order item has a quantity greater then 1000, cancelling the order item via the order form in backend does not work.
In the Demo (trunk) environment: the quantity of 1200 to cancel is displayed as "1,200" in the quantity input field.
--> an error is displayed
On my local installation I use a different locale and it is displayed as "1.200".
--> interprets the dot as a comma and the quantity of 1,2 is cancelled
To reproduce: go to ofbiz Demo
Create Order: Order Mgt --> Order Entry --> Sales Order (Customer: DemoCustomer) --> ProductId: GZ-2644, Quantity 1200 --> Finalize order
On order: Edit Items --> click checkbox next to quantity -->cancel selected items
