Is this a problem? I often do (om/set-state! owner :foo some-cursor) Can you explain some more what problem you are encountering? > > > On Tue, Sep 2, 2014 at 10:45 PM, Alan Shaw <[email protected]> wrote: >> >> My main app cursor has a field :circles which is a vector. My animator component's render-state method needs these circles transformed into animations. This is done by a function make-animations. The parent component invokes om/build on the animator, passing (:circles cursor) as the animator's cursor. >> >> I find that whenever I try to invoke the function on :circles, it is a cursor >> and may not be dereferenced.
