Hi everyone
im trying to add a line to a sublist via `Record.insertLine()` but i keep getting an error: `Failure: TypeError: Cannot read property 'isMultilineEditable' of null`
i know it is not anything in my code and i cant find any reference to it anywhere, have you encountered this before?

Its probably NetSuite trying (and failing) to validate that your sublist is editable

yea i think so, just dont know what to do about it

It might be one of the ones where you cant insert

Otherwise its something you do a support case for

im in edit mode on an estimate (item &gt; item list)
