[re-frame] Error when performing request immediately after init

[polymeris]

Calling martian/init and immediately dispatching a ::martian/request throws an error in ::on-complete: No protocol method ISet.-disjoin defined for type cljs.core/List

I think it is because re-frame/dispatch-sync is called in an async go block:

martian/re-frame/src/martian/re_frame.cljs

Line 60 in 6c1a3e6

(go (let [martian (<! (martian-http/bootstrap-swagger swagger-url params))]

Hi,

Yes, you are right - init is asynchronous because it involves an http call. You can use core.async/<! on the return value of init to block until it is ready, and then make your own call to Martian.

e.g.

(go (<! (martian/init "http://swagger.com")
    (re-frame/dispatch [::martian/request :some-operation {}]))

Thanks for the quick response. That solution should work.
