Something is not what you think it is.
This trace:

Means that EOEditingContext.faultForGlobalID did NOT find an EO for that global ID in that editing context. A few possibilities:
- this StockItem is not one of the ones you have pre-loaded
- you pre-loaded them in a different editing context
- something told the EC to forgetObject() after you pre-loaded them
