So, using om-classic, I find myself writing:
slipset 2017-09-04T10:38:01.000332Z
(dom/td nil (inc (aget (aget owner "props") "__om_index")))slipset 2017-09-04T10:38:25.000280Z
in a component which is built with om/build-all
slipset 2017-09-04T10:39:08.000053Z
RTFS’ing I see that om/build-all does
slipset 2017-09-04T10:39:11.000039Z
(map (fn [x i]
(build f x (assoc m ::index i)))
xs (range))

there is also standard library function map-indexed so you don’t have to use range
slipset 2017-09-04T10:39:41.000250Z
So I’d expect to find ::index in the opts map of my function, but the opts map seems to be nil
slipset 2017-09-04T10:40:10.000186Z
What I’m after is a way to easily get a hold of the index of the thing I’m building in om/build-all.
slipset 2017-09-04T12:19:44.000090Z
So, I guess what I’m looking for is (::index m) being passed in opts in

so changing (let [ret (f cursor' this opts)] ...) to (let [ret (f cursor' this (assoc opts ::index (::index m)))]...)
