I have a custom field that is a number based field with a lookup table in Project Online, I am unable to update this type of field with bulk edit. The drop down doesn’t even show up and dragging a item down from a project that does have the field populated yields the error of “Last Error: Invalid Custom Field Value”
I have a couple of small new features I am working on so the next update is not planned for a least a few weeks, however if in the interim I can find a quick fix for this specific bug then I will try to release that separately.
