Erpnext: V12.1.8: Table Multiselect field was erased/cleared after Save

[raymondliew1992]

As shown below, ‘Belongs to Company’ field is a table multiselect field I created in Customer doctype. Everytime when I save the customer, my selections in the field will be erased.

I was able to reproduce this on develop.

I solved this by ensuring that the field in the child table is marked as In Grid View.
