I have the following om component
(defn world-view [data owner opts]
(reify
om/IInitState
(init-state [_]
(om/transact! data [:world] (fn [] [])))
om/IWillMount
(will-mount [_]
(log (count (:world data))))
om/IRender
(render [_]
(apply dom/table nil
(om/build-all row (:world data))))))
I can log the count of the world property like above and it works as above.
But if I change IWillMount to the following:
om/IWillMount
(will-mount [_]
(go (while true
(log (:world data))
(let [world (<! (get-world data (:dimensions opts)))]
(om/! data #(assoc % :world world)))
(<! (timeout (:poll-interval opts))))))
The (log (:world data)) expression raises this error:
Uncaught Error: Cannot manipulate cursor outside of render phase, only
om.core/transact!, om.core/update!, and cljs.core/deref operations allowed
This is confusing to me because I can't see how I am manipulating the cursor.
Can anyone explain why this would happen?
