Separator option for select error if cell is null

Hi all,

I want to use the multiple and separator options for a select field type however the field may be empty in the datatable until it is edited. If the field initially has data everything works but when empty I get the following error: b is null - dataTables.editor.min.js:138:29, I guess becasue the field is null.

Can anyone help with this please?

I seem to be having a similar issue to the one discussed here:
