Hello, how actually insert_joined_row action works?
Im trying to insert joined row from A to B, but getting 'Cannot access 'joinTable' before initialization' error message.
Here's my field to join :
A table with reg_number field (string, unique, required), its unique generated by fill_formula_button at view.
B table with reg_number field key to A.reg_number.
at configuration it has relation A.reg_number but getting that error message.
