Yes, this help me. But something still not clear to me, if I have component A, B. B is rendered in A, and use a global singleton state {:app/x 0}. If I B has a query [:app/x] and A has query (om/get-query B), when I call (om/tansact! this-b ...) it will say has on query on this path. so I have to transact! with reconciler, is it correct?

not sure if this is relevant, the props in '(dom/div {:height 400 :width 500} "holder")' should has a tag #js.

Any good examples of recursive om.next parsers around that incorporate remote sync?
