Hi Anthony,

Sorry, but I think I'm not quite following the scenario fully.

Is the broken lookup a reference to a workbook's EntityId, or the parent container's?

If you go to /Projects and look at the row in core.Container and add EntityId to the grid (it's a hidden column), do you see the value in question?

If it's a workbook, can you see if targeting core.Workbooks instead of core.Containers gives a different result?

I'm off on vacation starting tomorrow, but hopefully Jon or others can chime in based on your response.

Thanks,
Josh
