Hi Chuck, The count is actually of the WebPage.childWebPages() array not on stockItems at all which is why I was puzzled that a StockItem.turnIntoFault() was being triggered. I confirmed that they are all in the same EC by logging the hashCode() of the EC (I assume that is valid) Thanks for your reply John
