So you have
Inventory
-qty
-cost
-msrp
->>lineItems
LineItem
-cost
-msrp
->inventory
You could set that up as a wizard creation page, something like
pageConfiguration = ‘CreateLineItem’ => displayPropertyKeys = (“[chooseInventory]”,”inventory”,”[editValues]”,”cost”,”msrp")
Such that you have to choose the inventory item and then proceed with editing the other values. Then do the validationKeys thing for Modern to copy your values. (In ponder, you’d override the _nextStep method on your subclass of R2DDefaultBranchDelegate.)
Then on save, you could adjust your inventory quantity in willInsert.. or maybe not. I don’t remember if willInsert is called a second time after a validation failure. (Or in ponder, you could override _save on your subclass of R2DDefaultBranchDelegate.)

When you select an inventory object, the pertinent attributes are copied to the line item entity. I want to copy these attributes to the line item as I may want to adjust (override) the values on a single report. Or if the purchase price of an inventory item changes, i do not want old reports (invoices) to show these new values.
