prev() in fillNA.with does not reference the updated DataRow

[n3utrino]

Might be a user error, but it feels like the statement

data.fillNA("ref").with { prev()!!.ref }

Should fill all the "ref" rows and not only the first empty one.

It should. Thank you for finding this problem :)

Actually it's more like missing documentation or API not being clear. It should work like this:

df.fillNA("ref").with { prev()?.newValue<String>() }
