Hi Steve,
The issue that you are facing is due to the fact that when the onExpandChange event fires for the detail row, you are mapping "result.data", which at this point contains a collection of the group items and not the data items. If you replace "result.data" with "products", you will notice that the expand will work. However, since the products will not contain the previous state, you will have to use a state variable that will hold a collection with the data items.
For your convenience, you can use the following example as a reference for enabling expand/collapse for groups and detail rows:
Hope this helps.

Hi Steve,
The state that you are using has "50" for the "take" and not all items are visible in the data (because this is the items collection for the first page). However, the aggregates are calculated without taking into account the paging and all items within the group are calculated. With that in mind, if you remove the "take" from the state you will notice that the aggregates are correctly calculated using all items within the group.
