Hi there,
When you have a long list of values in a List control under Product Categories in the Ecommerce management center and cause an error (duplicate value, space in the value etc.) there's an error message at the top of the page above the list. However, you don't see this error when you have a long list of values, which results in the user thinking that nothing happens when they click OK (see attachment).
Can the error be changed to an alert or moved to a visible location?
