After updating to Foodsoft v3.3.9+adam+ß there is a problem of adding articles to the total order. The
'Everyone' column and the tollerance bar zero out after refreshing the page.

I tested it on again with the foodcoopamsterdam demo on 3 different browser and 2 different machines.

In the screenshot of the interface , it is visible that though some orders should be full, none are marked to be ordered.

I found the source of the confusion. The shopping cart function has been added, therefore individual orders are not added to the Everyone column until paid for. This seems logical, But when you add or remove articles it still affects the units-to-order count in the Everyone column. This is only temporary - refreshing the page sets it back to zero.
This causes conflicts between the units-to-order column and the Amount column, when units-to-order can even show a negative quantity when removing article-units.

I got bitten by this today as well. It's even more confusing after the amount coloring.
This is the offending line (plus tolerance equivalent). Replacing it by

data_delta[:value_others] = order_article.quantity - \
  group_order_article.group_order_article_quantities.confirmed.sum(:quantity)

when the payorder plugin is enabled would do wonders. Haven't been able to do that in a somewhat clean way, though (deface messes up stuff).

I added a workaround for this. Better now?
