Why my javascript may load for a longlong time?

Ok, Gleb. Could you give me some more valuable advise how to make jscomponent act with ajax to java controller? To make component render instantly.

I’ve shown all possible ways of communication between the server-side and the client-side of the js-component. There should be no problems if these mechanisms are used correctly. I’ll be able to give you more valuable advice if you attach a working demo project along with a detailed description of what went wrong and how to reproduce the problem.
