Thought this was clear, sorry.

So I am at a doc, I want to check the save status of it. Basically equivalent of self.is_new() in server side. I tried using

cur_frm.doc.__islocal but it gave me undefined

if you have new doc it will be 1

Ah thanks. You’re right. Though I was expecting a 0 / False rather than undefined for already saved doctypes
