How to debug: jsaddle requests: 101 pending

[rubenmoor]

My reflex-dom application gets stuck in a weird state where an event that is supposed to occur never occurs.

Checking the "network" tab of the debugging tools I find two requests that never return:

The information I get from Google Chrome:

jsaddle 101 websocket jsaddle.js:9 0 B pending
jsaddle 101 websocket jsaddle.js:38 0 B pending

and no error in the output logs of ob run.

The code in jsaddle.js is

    var ws0 = new WebSocket(wsaddress);

and

                var ws1 = new WebSocket(wsaddress);

respectively.

I have no doubts there is some bug in my code but I am clueless on how to approach this. I eliminates the use of getPostBuild as this has been causing trouble before, but that wasn't it.
