Dynamic re-calculation of a sum of reference attributes

greg

I have checked that dynamic re-calculation does not work for a reference attribute. In my case this rule:

PurchaseOrder.TotalCost=PurchaseOrder.Freightcharge+SUM ItemOrder.ExtendedCost WHERE (ItemOrder IN PurchaseOrder.Items)

does not re-calculate the total cost of an order. Is there a way around or I have to live with it?

At the moment the dynamic re-calculation on forms does not work for aggregate operations like SUM and COUNT. You need to click Save on the form to get aggregate values updated.
