Steps to reproduce:
Open the trader building. Select an item you have in inventory at the trader that you can sell. Click in the quantity box to enter a specific amount. Hit enter when you are done typing.
What happens:
The counter returns to zero if you had moved the slider first, but in both cases, the Items to Trade display returns to “–” on both sides as if the slider was moved to zero.
What should happen:
After hitting enter, the slider should move to that value if it is within range, or to maximum or minimum value in the direction of the requested amount and the text amount will update. This should also change the Items to Trade display on the right with updated values.
Impact:
As it stands right now, the slider can represent a large set of values that are difficult to actually set if you want to buy or sell a specific amount. The values the slider can move to should be limited to the maximum that you can afford to sell or maximum that the trader can buy from you based on his current gold at the high end of the slider and equivalent restrictions at the low end. You should not be able to move the slider to a value you cannot complete a trade in.
