The resulted value (Cross site lkpup value) should be corrected not only the view but also in the display form. When I was using this feature in Edit form, it worked like a charm but when I try to use the resuling value in workflow, I started getting errors.
When Cross site lkpup value is rendered in edit form, it is fine. But it become (mostly) unusable once it is storing the value back to the form.
Any update/resolution in version 6.x?
