I have an input component that looks something like:
(defn handle-change! [e data edit-key owner]
(if (= (type data) om/MapCursor)
(om/update! data [edit-key]
(if (string? e) e (.. e -target -value)))))
(defn textarea [declaration owner {:keys [attribute] :as opts}]
(reify
om/IRender
(render [_]
(d/textarea {:value (attribute declaration)
:on-change #(handle-change! % declaration attribute
owner)}))))
and state that looks something like:
{:attribute "text"
:children {:child-key [{:ch-attr "text"}]}}
when I build the textarea with a cursor into the above state, it works just
fine, but when I build it with a cursor into a member of the children vector
(such as {:ch-attr "text"}), it throws an
"Uncaught Error: Cannot manipulate cursor outside of render phase, only
om.core/transact!, om.core/update!, and cljs.core/deref operations allowed" at
the om/update! line.
if I do something like, set-state! in handle-change!, add state to the
textarea, and update! the same cursor from within render-state, then it works
