Sorry for the long snippet. Can anyone help me figure out why I can't seem to find/use the

select

methods that I believe should be present for the record I'm manipulating in my browser console? (i.e. `rec.selectLine({"sublistId":"item",,"line":"0"})) Thank you! Additionally using

insertLine

doesn't seem to be working. I can successfully submit something and not get an error (

rec.insertLine({'sublistId':'item','line':'1','fieldId':'item','value':'Test Item_4'})

) but the line is not appearing in the browser (

rec.save

brings up an error though- "Please choose an item to add")
