The data source of the form was the table.selectedrow
but now that I have multiselect enabled on the table, the action button no longer selects the row, thus the form is empty.
this topic seemed to be close:
but the "currentRow" doesn't show up as a data source for the form, and although it doesn't throw an error, it's empty anyway.
I'm not sure where to go from here. I need multiselect to build a report from multiple records, but I also need the ability to edit individual records and child data in the form.
